Thermomechanical Processing of High-Strength Low-Alloy Steels considers some advanced techniques and metallurgical bases for controlled-rolling. This book contains 12 chapters. In Chapter 1, the purpose of thermomechanical processing and historical survey is described, while in Chapter 2, the kinetics of phase transformations and refinement of grain size in steels are elaborated. The techniques and metallurgical bases for controlled-rolling in the recrystallization, non-recrystallization, and (? + y) regions are reviewed in Chapters 3 to 5. Chapters 6 and 7 discuss the deformation resistance during hot-rolling and restoration processes. The phase transformations during cooling following hot-rolling are mentioned in Chapter 8, followed by a summarization of the effects of alloying elements in Chapter 9. Chapters 10 and 11 deal with the mechanical properties of controlled-rolled steel and prediction and control of microstructure and properties by thermomechanical processes. The problems faced and possibilities for future developments are stated in the last chapter. This publication is recommended for physicists, metallurgists, and researchers concerned with controlled-rolling, including non-specialists who have some knowledge of metallurgy.

Modern industry, driven by the recent environmental policies, faces an urgent need for the production of lighter and more environmentally-friendly components. High-strength low-alloy steels are key materials in this challenging scenario because they provide a balanced combination of properties, such as strength, toughness, formability, weldability, and corrosion resistance. These features make them ideal for a myriad of engineering applications which experience complex loading conditions and aggressive media, such as aeronautical and automotive components, railway parts, offshore structures, oil and gas pipelines, power transmission towers, and construction machinery, among others. The goal of this book is to foster the dissemination of the latest research devoted to high-strength low-alloy (HSLA) steels from different perspectives.

Because of the need for a better understanding of the effect of Arctic low temperature environments on the mechanical behavior of high-strength low-alloy (HSLA) steels, a comparative study has been undertaken to evaluate the effect of low temperature on the mechanical properties of two candidate steels, columbium-molybdenum "acicular ferrite" HSLA steel and high-columbium HSLA steel. The paper presents the data relating to the effect of low temperature on the mechanical properties, namely, dynamic fracture toughness KId properties, through instrumented impact testing of precracked Charpy V-notch samples and cyclic properties of the two steels. It also discusses the results in terms of their significance to material specification, selection, and performance criteria for safe and economical transportation of petroleum resources from the Canadian Arctic.

Behavior and Design of High-Strength Constructional Steel presents readers with extensive information on the behavior of high-strength constructional steels, providing them with the confidence they need to use them in a safe and economic manner to design and construct steel structures. The book includes detailed discussions on the mechanical properties of HHS while explaining the latest progress in research and design guidelines, including material properties at ambient and elevated temperatures. In addition, the book explains the behavior of elementary members subject to different types of loads and load combinations, and those that are integral to the design of bolted and welded connections. The hysteretic behavior of HHS materials and members are also discussed. This is critical for application and designs under earthquakes and fire conditions. The buckling behaviors of HSS box-section and H-section columns are included in terms of experimental and numerical investigations, along with the geometric imperfection induced by welding. Provides a comprehensive review on the topic of high-strength constructional steel and the latest progress in research and design guidelines Explains the behavior of elementary members subjected to different types of loads and load combinations Recommends structural systems for using high-strength constructional steels in seismic zones

The sections in this book are devoted to new approaches and usages of stainless steels, the influence of the environments on the behavior of certain classes of steels, new structural concepts to understand some fatigue processes, new insight on strengthening mechanisms, and toughness in microalloyed steels. The kinetics during tempering in low-alloy steels is also discussed through a new set-up that uses a modified Avrami formalism.
