This book describes the fundamentals of residual stresses in friction stir welding and reviews the data reported for various materials. Residual stresses produced during manufacturing processes lead to distortion of structures. It is critical to understand and mitigate residual stresses. From the onset of friction stir welding, claims have been made about the lower magnitude of residual stresses. The lower residual stresses are partly due to lower peak temperature and shorter time at temperature during friction stir welding. A review of residual stresses that result from the friction stir...

This book provides a complete review of the current state of the art in the field of high entropy alloys (HEA). The conventional approach to alloy design is to select one principal element and add elements to it in minor quantities in order to improve the properties. In 2004, Professor J.W. Yeh and his group first reported a new approach to alloy design, which involved mixing elements in equiatomic or near-equiatomic proportions, to form multi-component alloys with no single principal element. These alloys are expected to have high configurational entropy and hence were termed as "high...

Primer on Flat Rolling is a fully revised second edition, and the outcome of over three decades of involvement with the rolling process. It is based on the author's yearly set of lectures, delivered to engineers and technologists working in the rolling metal industry. The essential and basic ideas involved in designing and analysis of the rolling process are presented.

The book discusses and illustrates in detail the three components of flat rolling: the mill, the rolled metal, and their interface. New processes are also covered; flexible rolling and accumulative...

Describes the weldability aspects of structural materials used in a wide variety of engineering structures, including steels, stainless steels, Ni-base alloys, and Al-base alloys

Welding Metallurgy and Weldability describes weld failure mechanisms associated with either fabrication or service, and failure mechanisms related to microstructure of the weldment. Weldability issues are divided into fabrication and service related failures; early chapters address hot cracking, warm (solid-state) cracking, and cold cracking that occur during initial fabrication, or repair....

Advanced composite materials for bridge structures are recognized as a promising alternative to conventional construction materials such as steel.

After an introductory overview and an assessment of the characteristics of bonds between composites and quasi-brittle structures, Advanced Composites in Bridge Construction and Repair reviews the use of advanced composites in the design and construction of bridges, including damage identification and the use of large rupture strain fiber-reinforced polymer (FRP) composites. The second part of the book presents key applications of...

Spawned by growing interest in ultrasonic technology and new developments in ultrasonic melt processing, the Second Edition of Ultrasonic Treatment of Light Alloy Melts discusses use of ultrasonic melt treatment in direct-chill casting, shape casting, rapid solidification, zone refining, and more, exploring the effects of power ultrasound on melt degassing, filtration, and refinement in aluminum and magnesium alloys. The fully revised and restructured Second Edition:

• Contains new, in-depth coverage of composite and nanocomposite materials
