Book Description
To meet the challenge of transporting mineral and energy resources from the Canadian North as well as the need to conserve materials and energy, many new high-strength low-alloy (HSLA) steels have been and are being developed. This paper presents the results of the effect of low-temperature environments on steels. Four Arctic HSLA steels, a dual-phase steel, three experimental HSLA weathering steels and three experimental boron-HSLA steels have been used in the study. Tension tests have been carried out from room temperature to -196°C (-321°F) to evaluate the formability parameters (mainly uniform elongation and strain hardening exponent). Instrumented impact tests have also been carried out on the dual-phase steel to study its ductility under high rates of deformation. The relevance of this study to formability practice (in situ as well as "shop") of HSLA steels are pointed up. The areas where further work is needed are also discussed.

Book Description
Advanced high-strength steels (AHSS) are a family of steels that are stronger than most steels and have better formability than today’s conventional high-strength steels. New U.S. safety and fuel economy regulations have intensified pressure on OEMs to reduce vehicle weight. These pressures are causing auto companies to rethink alternative material applications and to look for opportunities that steel offers. The purpose of this book is to provide information for engineers who are designing the next generation of lighter vehicles. The material in the book is presented to help them make informed decisions on what basic materials to use and how to optimize those materials to achieve cost-effective weight reduction. The emphasis is on steels in general and AHSS in particular. However, there is much information on comparisons of steel with alternative materials for different subsystems of the vehicle. To support the latest automotive challenges in terms of weight reduction, this book lays out the opportunities for alternative material use in automobiles and offers the most up-to-date design guidance in efficient architectures that use AHSS. It simultaneously explores weight savings and resulting fuel economy advantages of a strategic usage of AHSS. Realistic comparisons with other alternative materials are made through detailed analyses. It also offers test cases that demonstrate how AHSS technology has developed. The focus of the text is on body and chassis structures and the sheet metal of which these systems are primarily made. More of the content addresses the automotive body, as this is where most of the AHSS are being applied today. The past, present, and future of AHSS are covered, as well as competing technologies such as aluminum sheet metal.

Book Description
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.
