This chapter presents an overview on the twins and stacking faults. It then provides an overview of the compositions, microstructures, thermodynamics, processing, deformation mechanism, mechanical properties, formability, and special attributes of twinning-induced plasticity steels.

This chapter briefly discusses the characteristics of mechanical twins and stacking faults in close-packed planes. It provides an overview of the composition, microstructures, thermodynamics, processing, deformation mechanism, mechanical properties, formability, and special attributes of twinning-induced plasticity steels.

This chapter discusses various alloying and processing approaches to increase the strength of low-carbon steels. It describes hot-rolled low-carbon steels, cold-rolled and annealed low-carbon steels, interstitial-free or ultra-low carbon steels, high-strength, low-alloy (HSLA) steels, dual-phase (DP) steels, transformation-induced plasticity (TRIP) steels, and martensitic low-carbon steels. It also discusses twinning-induced plasticity (TWIP) steels along with quenched and partitioned (Q&P) steels.

The performance attributes of advanced high-strength steels are summarized in this chapter. These attributes include stiffness, strength, strain hardening, fatigue, crashworthiness, formability, toughness, and bake hardening.

This chapter discusses the compositions, metallurgical phases, microstructure, heat treatment, grades, and structure-property relationships of steels. In addition, it describes the mechanisms involved in deformation, strengthening, and annealing of steels.

This chapter presents the nomenclature, generations, thermomechanical processing, microstructure development, and mechanical properties of advanced high-strength steels.

This chapter summarizes the microstructural basis of conventional high-strength steels (HSS) and the three generations of advanced high-strength steels (AHSS). It presents the requirements of a third generation advanced high-strength steel and its microstructural design. The chapter also includes a discussion about novel AHSS processing routes: quenching, partitioning, and double-stabilization thermal cycling.

This chapter presents a review of some of the global development and deployment of advanced high-strength steels (AHSS). It discusses collaboration projects between government, industry, and academia and summarizes research that has focused on the influence of alloy composition on the microstructure evolution during plastic deformation and the resulting mechanical properties.
