Advanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. However, due to the metallurgical complexity of AHSSs, it is impossible to roll all of the AHSS grades in a rolling mill with the same rolling technology. Each of AHSSs has unique applications in vehicles, and specified rolling technologies are required to produce high quality AHSS products where they might be the best employed to meet performance demands of the automotive parts. Such background has prompted the publication of this scholarly book in the area of rolling of AHSSs with a purpose of providing readers with a valuable technical document that can be used in the research and development of AHSSs for automotive and other manufacturing industries. With contributors from USA, Germany, Poland, Italy, Spain, Austria, Australia, China, India and Iran, the book highlights the latest advances in rolling technologies of AHSSs. It focuses on the theory, simulation and practice of the rolling of AHSSs: The book introduces the history, types and advances of AHSSs and their processes; proposes new theory that is applicable to the rolling of AHSSs, presents mathematical and numerical modelling of AHSSs in rolling; covers thermomechanical processing technologies of AHSSs; provides case studies on the rolling practice of the most popular AHSSs and includes other rolling-related technologies of AHSSs. The book will be useful for both theoretical and applied research aimed at AHSSs rolling technologies, and will be a scientific and valuable literature for the metallurgists, engineers, materials scientists, academics and graduate students who are studying and working with AHSSs and their rolling technologies worldwide.

Microforming Technology: Theory, Simulation and Practice addresses all aspects of micromanufacturing technology, presenting detailed technical information and the latest research developments. The book covers fundamentals, theory, simulation models, equipment and tools design, practical micromanufacturing procedures, and micromanufacturing-related supporting systems, such as laser heating system, hydraulic system and quality evaluation systems. Newly developed technology, including micro wedge rolling, micro flexible rolling and micro hydromechanical deep drawing, as well as traditional methods, such as micro deep drawing, micro bending and micro ultrathin strip rolling, are discussed. This will be a highly valuable resource for those involved in the use, study and design of micro products and micromanufacturing technologies, including engineers, scientists, academics and graduate students.

Tungsten alloying in microalloyed steels is of growing academic and industrial interests due to its positive role in the aspects of microstructural modification and properties improvement. This book has systematically described the functions of tungsten alloying in microalloyed steels. Topics covered include the effects of tungsten on the phase transformation behaviour of microalloyed steels by establishing the continuous cooling transformation diagrams in order to control the expected microstructure and the required mechanical properties; the effects of tungsten on the characteristics of precipitated particles in microalloyed steels; the microstructural evolution of microalloyed steels including grain size, phase component, pearlite interlamellar spacing, allotriomorphic ferrite and acicular ferrite after tungsten addition; the effects of tungsten on mechanical properties of microalloyed steels by means of hardness, impact toughness and room/low-temperature tensile properties tests; strategies for heat treatment of microalloyed steels with the purpose of determining the optimal heat treatment conditions for microalloyed steels with different tungsten additions; improvement of the corrosion resistance of microalloyed steels after tungsten addition; and the effects of tungsten on the hydrogen embrittlement behaviour of microalloyed steels. The text of this book is up-to-date, informative, readable and self-contained. It is not only a technical document that can be used in the research and development of tungsten alloying in microalloyed steels, but also a scientific and valuable literature for the metallurgists, engineers, materials scientists, academics and higher degree research students who make, use, study and design with steels and tungsten worldwide by introducing the latest research findings and achievements of tungsten alloying in microalloyed steels, and considering the metallurgical basis for steel research.
