Das vorliegende Buch erscheint als Ersatz fur die beiden Werke des Verlages uber Kolbenverdichter von F. Froehlich sowie von Ch. Bouche und K. Wintterlin, die als Ziel hatten, das erforderliche Wissen fur die Auslegung, die Konstruktion und Be- trieb dieser Maschinen zu vermitteln. Dabei galt der, Froehlich' als internationales Standardwerk und der, Bouche' als leicht fassliche Einfuhrung fur Studenten. Bei- de aber zeigen schon das vielseitige Wissen aus der Thermodynamik, der Mecha- nik, der Festigkeitslehre, der Maschinenelemente, der Regelungs- und der Ferti- gungstechnik, welche die Beherrschung der Kompressoren erfordert. Seit dem Erscheinen dieser Werke wurden die oben erwahnten Wissenschaften starker strukturiert, neuere Betrachtungsweisen eingefuhrt, die Rechenverfahren verfeinert und die Herstellungsmethoden vervollkommnet. Dies ermoeglichte der Siegeszug der Computer, die immer groessere Datenmengen verarbeiten und daher immer kompliziertere Arbeitsmethoden zulassen. So entstanden umfangreiche Programme fur die finiten Elemente in der Mechanik, fur CAD und CAM fur die Konstruktion und die Fertigung sowie spezielle Firmenprogramme fur die Ausle- gung. Damit erfolgte die Auswertung immer schneller und exakter, aber auch das Er- kennen innerer Zusammenhange und die Beurteilung der Brauqhbarkeit der Ergeb- nisse wurde fur unerfahrene jungere Ingenieure und Studenten immer schwieriger. Um diesem Mangel zu begegnen, enthalt dieses Buch viele Zahlen- und Konstruk- tionsbeispiele, die Berechnung und Entwurf vereinfacht zeigen. Sie sollen helfen, spater die Computerresultate richtig zu deuten. Hierzu dient auch die weitreichen- de Diskussion der technischen und physikalischen Probleme und die eingehende Beschreibung des Betriebs der Maschinen. Auf die hier nicht behandelten Proble- me verweist ein ausfuhrliches Schrifttumverzeichnis.

In der vollstandig uberarbeiteten Auflage ist die Projektaufgabe durch die zusatzliche Angabe der physikalischen Einheit deutlich nachvollziehbarer geworden. Ein neues Sachwortverzeichnis ermoglicht ein schnelles Auffinden der gesuchten Aufgaben."

From conventional welding techniques to electron or laser beam, this book provides a comprehensive overview about processes, metallurgy, quality assessment, testing, and numerical simulation in welded structures.

The opening chapter provides a comprehensive insight into dissimilar materials joined by FSW technology. FSW parameters such as tool design, tool pin offset, rotational speed, welding speed, tool tilt angle and position of workpiece material in the fixture for dissimilar materials are summarized. In the next chapter the author confirms the emission of particles in the nanorange during FSW of the most commonly used aluminium alloys, AA 5083 and AA 6082, which are originated from the aluminium alloy itself, due to friction of the welding tool against the workpiece. In the closing chapter, feasibility to join 2.5 mm thick AA5052 aluminium alloy and 1.4 mm thick high strength steel, DP590, by conventional FSW process (FSW) and TIG-assisted HFSW process (HFSW) is studied through couple experimental and numerical analysis. A comparative study in joining of dissimilar materials by conventional FSW and HFSW processes is performed to realize the effect of different welding parameters on the growth of IMC layer thickness.

Electrospinning is a simple and efficient process in producing nanofibers. The use of an electrospinning process in fabricating tissue engineering scaffolds has received great attention in recent years due to its simplicity and ability to fabricate ultrafine nanofibers. Chapter One investigates the process of formation of ultrafine fibres and nonwoven membranes by electrospinning from natural degradable polymers -- polyhydroxyalkanoates (PHAs); physical, mechanical, and biological properties of the products have been included. Chapter Two aims to give an insight into the use of this interesting class of polymers in electrospinning as well as to explore the wide range of possible applications. Chapter Three reveals the fundamental working principles of electrospinning process and the effect of electrospinning process parameters towards the nanofibers morphology. Chapter Four provides detailed information on the background of electrospinning, fundamental principles and theory, investigation on parameters involved in nanofibers structural/ biological/mechanical characteristics, advantages of superb properties and biomedical applications of electrospun nanofibres, particularly in tissue engineering heart valves. Chapter Five focuses on the fabrication and characterisation of electrospun PVDF, PVDF/PLA (50/50 wt %) and PVDF/G (99.5/0.5 wt %) membranes. Chapter Six presents the main results of recent experimental investigation of the electrodeposition and characterisation of Fe/TiO2 composite coatings obtained from an environmentally friendly methanesulfonate iron plating bath containing colloidal TiO2 particles.

In friction stir welding (FSW) of two similar or dissimilar metals, the work materials are positioned in such a way against a rotating-travelling stirring tool that allow FSW operations to be performed. The operation is begun by pushing the bottom of rotating tool pin against the initial position of weldment to be produced along desired welding line. The push by the bottom of rotating tool pin on the surface of work materials to be welded is made in order to generate local heating by mechanical friction. This book examines the weldment formation in friction stir welding.

At the beginning of the twentieth century Britain was amongst the world leaders in the production of machine tools, yet by the 1980s the industry was in terminal decline. Focusing on the example of Britain's largest machine tool maker, Alfred Herbert Ltd of Coventry, this study charts the wider fortunes of this vital part of the manufacturing sector. Taking a chronological approach, the book explores how during the late nineteenth century the industry developed a reputation for excellence throughout the world, before the challenges of two world wars necessitated drastic changes and reorganisations. Despite meeting these challenges and emerging with confidence into the post-war market place, the British machine tool industry never regained its pre-eminent position, and increasingly lost ground to foreign competition. By using the example of Alfred Herbert Ltd to illuminate the broader economic and business history of the British machine tool industry, this study not only provides a valuable insight into British manufacturing, but also contributes to the ongoing debates surrounding Britain's alleged decline as a manufacturing nation.
