This book focuses on the fundamental concept of and current
endeavors in "urban mining" among those who are interested in both
metal resources and ecology. Systems for recycling and reusing
precious metals and rare-earth minerals contained in used and
discarded electronics are introduced in this book. The target
audience is not academic researchers in the resource management and
ecology fields but, rather, citizens who are concerned about our
future environment and want to do something for the future.
"Biomimetics in Materials Science" provides a comprehensive
theoretical and practical review of biomimetic materials with
self-healing, self-lubricating and self-cleaning properties. These
three topics are closely related and constitute rapidly developing
areas of study. The field of self-healing materials requires a new
conceptual understanding of this biomimetic technology, which is in
contrast to traditional engineering processes such as wear and
fatigue. "Biomimetics in Materials Science" is the first monograph
to be devoted to these materials. A new theoretical framework for
these processes is presented based on the concept of multi-scale
structure of entropy and non-equilibrium thermodynamics, together
with a detailed review of the available technology. The latter
includes experimental, modeling, and simulation results obtained on
self-healing/lubricating/cleaning materials since their emergence
in the past decade."
This authoritative book covers everything an engineer needs to know about manufacturing systems and processes. It presents over 400 manufacturing processes and uses a systems orientation to manufacturing.
The book describes the valorization of biomass-derived compounds
over gold catalysts. Since biomass is a rich renewable feedstock
for diverse platform molecules, including those currently derived
from petroleum, the interest in various transformation routes has
become intense. Catalytic conversion of biomass is one of the main
approaches to improving the economic viability of biorefineries. In
addition, Gold catalysts were found to have outstanding activity
and selectivity in many key reactions. This book collects
information about transformations of the most promising and
important compounds derived from cellulose, hemicelluloses, and
woody biomass extractives. Since gold catalysts possess high
stability under oxidative conditions, selective oxidation reactions
were discussed more thoroughly than other critical reactions such
as partial hydrogenation, acetalization, and isomerization. The
influence of reaction conditions, the role of the catalyst, and the
advantages and disadvantages of using gold are presented for all of
the reactions mentioned above. This book provides an overview of
the recent research results focusing on application of gold
catalysts for synthesis of valuable chemicals using renewable
feedstocks.
In the past twenty years, new experimental approaches, improved
models and progress in simulation techniques brought new insights
into long-standing issues concerning dislocation-based plasticity
in crystalline materials. During this period, three-dimensional
dislocation dynamics simulations appeared and reached maturity.
Their objectives are to unravel the relation between individual and
collective dislocation processes at the mesoscale, to establish
connections with atom-scale studies of dislocation core properties
and to bridge, in combination with modelling, the gap between
defect properties and phenomenological continuum models for plastic
flow. Dislocation dynamics simulations are becoming accessible to a
wide range of users. This book presents to students and researchers
in materials science and mechanical engineering a comprehensive
coverage of the physical body of knowledge on which they are based.
It includes classical studies, which are too often ignored, recent
experimental and theoretical advances, as well as a discussion of
selected applications on various topics.
During the translation, the author had the opportunity to re view
several chapters, taking into consideration the more recent
literature. As far as possible all new theoretical concepts and
experi mental data published before 1963 have been quoted and
discussed under the theoretical viewpoint of this book. A new
chapter "Passivity and Inhibition During High-Tempera ture
Oxidation" was introduced. Section 4.8 was enlarged by a dis
cussion of the transition from internal to external oxidation. The
author very much appreciates the cooperation of the trans lator and
of Plenum Press. Gottingen, April 1.965 Karl Hauffe v Preface The
number of publications concerned with oxidation and cor rosion
processes has become so copious that many engineers and scientists
find it practically impossible to obtain an overall view of the
growing body of knowledge and to bring order to the confusing
multiplicity of experimental data. As a result the need for a
compre hensive survey of the present state of research in this
field has be come more and more urgent."
Die "Klassiker der Technik" sind unveranderte Neuauflagen
traditionsreicher ingenieurwissenschaftlicher Werke. Wegen ihrer
didaktischen Einzigartigkeit und der Zeitlosigkeit ihrer Inhalte
gehoeren sie zur Standardliteratur. Hintergrunde vieler
computergestutzter Verfahren erschliessen sich erst durch das
Studium dieses klassischen Wissens. In dem Klassiker zur Korrosion
der Metalle wird der Stoff systematisch und didaktisch durchdacht
dargestellt. Dabei beschrankt sich der Autor auf das Wesentliche
und erlautert dennoch eine Fulle von Einzelfragen.
Considered a major field of photonics, plasmonics offers the
potential to confine and guide light below the diffraction limit
and promises a new generation of highly miniaturized photonic
devices. This book combines a comprehensive introduction with an
extensive overview of the current state of the art. Coverage
includes plasmon waveguides, cavities for field-enhancement,
nonlinear processes and the emerging field of active plasmonics
studying interactions of surface plasmons with active media.
Developed by the late metallurgy professor and master
experimentalist Hubert I. Aaronson, this collection of lecture
notes details the fundamental principles of phase transformations
in metals and alloys upon which steel and other metals industries
are based. Mechanisms of Diffusional Phase Transformations in
Metals and Alloys is devoted to solid-solid phase transformations
in which elementary atomic processes are diffusional jumps, and
these processes occur in a series of so-called nucleation and
growth through interface migration. Instead of relying strictly on
a pedagogical approach, it documents the evolution of phase
transformation concepts. The authors present topics by describing a
phenomenon and then following up with a corresponding hypothesis or
alternative explanation. In this way, the book also shows how the
field continues to evolve and meet new challenges. Integrated with
information from a number of key papers and review articles, this
volume reflects this revered and influential instructor's unique
and passionate way of introducing well-established theories and
knowledge in a systematic way, at the same time introducing, in
great detail, how a new idea or interpretation of a phenomenon has
emerged, evolved, and gained its current status. If the published
version of a theory or a model was too condensed, Aaronson worked
the problem out in painstaking detail so that graduate students
could follow the derivations. This collection is full of such
unique "Aaronsonian idiosyncrasies," which add immense value as a
powerful tool for learning in this challenging materials field.
Metallic (magnetic and non-magnetic) nanocrystalline materials have
been known for over ten years but only recent developments in the
research into those complex alloys and their metastable amorphous
precursors have created a need to summarize the most important
accomplishments in the field. This book is a collection of articles
on various aspects of metallic nanocrystalline materials, and an
attempt to address this above need. The main focus of the papers is
put on the new issues that emerge in the studies of nanocrystalline
materials, and, in particular, on (i) new compositions of the
alloys, (ii) properties of conventional nanocrystalline materials,
(iii) modeling and simulations, (iv) preparation methods, (v)
experimental techniques of measurements, and (vi) different modern
applications. Interesting phenomena of the physics of
nanocrystalline materials are a consequence of the effects induced
by the nanocrystalline structure. They include interface physics,
the influence of the grain boundaries, the averaging of magnetic
anisotropy by exchange interactions, the decrease in exchange
length, and the existence of a minimum two-phase structure at the
atomic scale. Attention is also paid to the special character of
the local atomic ordering and to the corresponding interatomic
bonding as well as to anomalies and particularities of electron
density distributions, and to the formation of metastable,
nanocrystalline (or quasi-crystalline) phases built from
exceptionally small grains with special properties. Another
important focus of attention are new classes of materials which are
not based on new compositions, but rather on the original and
special crystalline structure in the nanoscale.
This second edition of C02 Laser Cutting , examines, and in places updates, the whole subject of co2 laser cutting. As with the original, the style is conversational and readable, with mathematical treatments kept to a minimum to give it its uniquely accessible feel. The discussion covers the cutting of metals and non metals on a wide range of levels, from practical advice and processing parameters to explanations of the physical and chemical reactions which take place in the cut zone. Materials covered include steels, wood, ceramics, polymers and non-ferrous alloys, and the information is taken from an extensive range of experimental and commercial results. The cutting process is dealt with in two ways: Practically - for the hands-on operator. Technically - for the researcher or scientist. The user-friendly yet informative style makes this both a practical handbook and research textbook, and is invaluable to anyone concerned with laser cutting, from job shop machine operators to post graduate researchers.
This book addresses the chemistry of the second and third row d-block metals, assuming a knowledge of the chemistry of the first row metals.

This book provides an advanced level introduction to the electrochemistry. It provides the background required to follow current research in a subject which has again become highly topical through the recent development of surface sensitive techniques. It is divided into three parts covering the fundamentals of the subject, the experimental methods including surface sensitive techniques, and a few important problems in theoretical electrochemistry. A special chapter is devoted to liquid-liquid interfaces which have become of interest because of their relation to biological membranes.
Due to unusually high operating temperatures, intense radiation,
viscous slags, dense metals, and other factors, the design and
operation of metallurgical processes is an especially demanding
task. This volume describes the engineering principles involved in
this industry, beginning with an introduction to the basic
mechanisms of heat, mass, and fluid flow, while showing the origin
of associated transport coefficients: diffusivity, conductivity,
and viscosity. The discussions are supplemented with examples and
exercises. Empirical techniques for modelling and process design
are presented, followed by numerical techniques and computer
programs needed for "ground-up" quantitative descriptions of
typical metallurgical processes. A generous appendix provides a
wealth of detail on the thermodynamic and physical properties of
substances commonly encountered by metallurgists, while a short
section on metallurgical thermodynamics illustrates the way these
tabulations should be used. The paperback edition has been
corrected and updated, while a new section on the numerical
simulation of flow processes has been added. A key text for
engineers, scientists, and students, this book offers a unique look
at the rich variety of phenomena that govern the behavior and
kinetics of metallurgical processing operations.
At one time, most towns of any size had somewhere a small foundry
that would undertake small casting jobs, often more out of interest
and good neighbourliness than for commercial gain. Regrettably,
those days are no more and the model engineer in many areas must
either adapt commercially available castings or send away to a
specialist foundry that will undertake small jobs, often at some
expense and with some delay. The alternative is to make your own
patterns and castings, which is in fact much easier than you may
think. The Backyard Foundry covers basic principles, materials and
techniques, pattern making, moulding boxes, cores and core-boxes,
electric, gas and coke furnaces, and includes step-by-step
procedures with examples of locomotive cylinders and wheels.
Sources of specialised materials and even the design of an outdoor
furnace suitable for small-scale commercial work are given. Each
stage and subject is covered in detail so that even the
inexperienced can undertake casting with confidence. Although the
book is written primarily for the model engineer, anyone wishing to
make mouldings or castings will profit from its pages.
This compilation of two previous Canada Department of Mines titles,
"The Physical Properties of the Metal Cobalt" (H.T. Kalmus), and
"Cobalt--Its Occurrence, Metallurgy, Uses and Alloys" (Charles W.
Drury), includes some minor corrections and additions. (Technology
& Industrial Arts)
Corrosion causes permanent damage to metal surfaces and is a major
global challenge, spanning numerous fields including industrial
sectors, construction materials, and surface treatments for
metallic cultural heritage preservation. Nanomaterials and
nanocomposites can be used as effective alternative corrosion
inhibitors in the place of traditional environmentally toxic
substances. This book provides readers with an overview of the
properties and applications of nanomaterials and nanocomposites as
corrosion inhibitors. Chapters first cover the basics of
nanomaterials and the features that make them useful candidates,
before highlighting recent advances from across the field for
industry-oriented challenges. With a focus on cutting-edge
research, this book is a valuable resource for chemists, chemical
engineers, material scientists and environmental chemists in both
academia and industry who want to learn more about corrosion
inhibitors and mechanisms.

The correct determination of stresses in rolling mills is of great
practical importance in designing modern high-capacity mills. In
the present text Academician A. Tselikov sets forth, on the basis
of his original works, the principles of the applied theory of
stress analysis in rolling, in order to help designers and
technologists to make these calculations in a more correct and
substantiated way.The book presents the principles of the theory of
plasticity, contains data on the distribution of stresses and
strains over a section of a strip being rolled, as well as an
analysis of the various forces applied to rolls. The book also
describes methods of computing rolling torques, and the forces
acting in die, cross and helical rolling.This text is intended for
students of higher technical schools. It will also be useful for
engineers specializing in the design and operation of rolling
mills.
