This chapter provides an overview of the composition, microstructures, processing, deformation mechanism, mechanical properties, formability, and special attributes of complex-phase steels.

This chapter presents a discussion on the compositions, microstructures, processing, deformation mechanism, mechanical properties, formability, and attributes of complex-phase steels.

This chapter discusses the properties and behaviors of advanced high-strength steels used in the automotive industry, including dual- and complex-phase steels, transformation-induced plasticity steels, ferritic-bainitic steels, and quenched and partitioned steels. It explains how different manufacturing processes, including coating, affect the grain size, microstructure, and formability of these important 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 provides an overview of the nomenclature, generations, and thermomechanical processing of advanced high-strength steels (AHSS) and provides information on the development of microstructure. It also presents a review of the mechanical property trends of AHSS.

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 discusses ultra-high-strength steels (UHSS) and gigapascal (GPa) steels and discusses the global formability diagram.

This chapter provides an overview of a computational method, called CALPHAD, used for the study of phase equilibria in multicomponent systems. It describes the thermodynamic models and calculation techniques employed in the software and explains how it applies to complex alloys used in industry. It also provides examples showing how CALPHAD has been used to determine the formability of metallic glass, calculate the dilation of stainless steel during phase transformation, and predict the beta transus and approach curves of commercial titanium alloys.

This chapter discusses the forming characteristics of dual-phase (DP) and transformation-induced plasticity (TRIP) steels. It begins with a review of the mechanical behavior of advanced high-strength steels (AHSS) and how they respond to stress-strain conditions associated with deformation processes such as stretching, bending, flanging, deep drawing, and blanking. It then describes the complex tribology of AHSS forming operations, the role of lubrication, the effect of tool steels and coatings, and the force and energy requirements of various forming presses. It also discusses the cause of springback and explains how to predict and compensating for its effects.
