Monitoring and control of microstructure evolution in metal
processing is essential in developing the right properties in a
metal. Microstructure evolution in metal forming processes
summarises the wealth of recent research on the mechanisms,
modelling and control of microstructure evolution during metal
forming processes.
Part one reviews the general principles involved in understanding
and controlling microstructure evolution in metal forming.
Techniques for modelling microstructure and optimising processes
are explored, along with recrystallisation, grain growth, and
severe plastic deformation. Microstructure evolution in the
processing of steel is the focus of part two, which reviews the
modelling of phase transformations in steel, unified constitutive
equations and work hardening in microalloyed steels. Part three
examines microstructure evolution in the processing of other
metals, including ageing behaviour in the processing of aluminium
and microstructure control in processing nickel, titanium and other
special alloys.
With its distinguished editors and international team of expert
contributors, Microstructure evolution in metal forming processes
is an invaluable reference tool for metal processors and those
using steels and other metals, as well as an essential guide for
academics and students involved in fundamental metal research.

The objective of this publication is to comprehensively discuss
the possibilities of producing steels with pre-determined
attributes, demanded by the customer to fit exacting
specifications. The information presented in the book has been
designed to indicate the reasons for the expenses and to aid in the
process of overcoming the difficulties and reducing the costs.
In nine detailed chapters, the authors cover topics including:
steel as a major contributor to the economic wealth of a country in
terms of its capabilities and production current concerns of major
steel producers phenomena contributing to the quality of the
product information concerning the boundary conditions of the
rolling process and initial conditions, put to use by mathematical
models the solid state incremental approach and flow formulation
parameters and variables - most of which make use of the
exponential nature of phenomena that are activated by thermal
energy the application of three dimensional analysis to shape
rolling the evaluation of parameters by a form of inverse analysis
to the flat rolling process knowledge based modeling, using
artificial intelligence, expert systems and neural networks
They conclude that when either mathematical or physical modeling of
the rolling process is considered and the aim is to satisfy the
demands for customers, it is possible to produce what the customer
wants, exactly.

Computational Materials Engineering: Achieving High Accuracy and
Efficiency in Metals Processing Simulations describes the most
common computer modeling and simulation techniques used in metals
processing, from so-called "fast" models to more advanced
multiscale models, also evaluating possible methods for improving
computational accuracy and efficiency. Beginning with a discussion
of conventional fast models like internal variable models for flow
stress and microstructure evolution, the book moves on to advanced
multiscale models, such as the CAFE method, which give insights
into the phenomena occurring in materials in lower dimensional
scales. The book then delves into the various methods that have
been developed to deal with problems, including long computing
times, lack of proof of the uniqueness of the solution,
difficulties with convergence of numerical procedures, local minima
in the objective function, and ill-posed problems. It then
concludes with suggestions on how to improve accuracy and
efficiency in computational materials modeling, and a best
practices guide for selecting the best model for a particular
application.
