About this book

This book summarizes the advanced manufacturing technology of original innovations in hot stamping of lightweight car body. A detailed description of the technical system and basic knowledge of sheet metal forming is given, which helps readers quickly understand the relevant knowledge in the field. Emphasis has been placed on the independently developed hot stamping process and equipment, which help describe the theoretical and experimental research on key problems involving stress field, thermal field and phase transformation field in hot stamping process. Also, a description of the formability at elevated temperature and the numerical simulation algorithms for high strength steel hot stamping is given in combination with the experiments. Finally, the book presents some application cases of hot stamping technology such as the lightweight car body design using hot stamping components and gradient hardness components, and the cooling design of the stamping tool.

This book is intended for researchers, engineers and graduate students in vehicle engineering, mechanical engineering, especially in the field of advanced manufacturing technology. The book also provides a useful reference for other new technology related temperature and phase transformation, such as aluminum-magnesium alloy hot stamping.

Chapter 1. The Basis of Sheet Metal Forming Technology
Abstract
Metal pressure processing, also known as metal plastic working, is a kind of manufacturing method, which makes use of metal plastic deformation caused under external force to obtain raw materials, blanks, or components with certain shape, size, and mechanical property.

Chapter 2. Hot Stamping Technology and the Main Equipment
Abstract
In recent years, automotive lightweight has led to the increasing demand of high strength steel (HSS) auto parts. Lots of correlative companies and research institutes in America, Europe, Japan, and China have invested large amount of energy into the research of advanced automotive HSS forming technology.

Chapter 4. The Basic Theory and Constitutive Equation of High Strength Steel for Hot Forming
Abstract
In the front section of this book, we briefly describe the basic principle of high strength steel for hot stamping technology. The special boron alloy steel is heated to make the austenitic change. Then the red-hot sheet metal is put into a mold with cooling system to form.

Chapter 5. Constitutive Integration Algorithm of Crystal Thermal Deformation
Abstract
The uniform stress–strain curves are used to describe the material properties in the calculation of macroscopic finite element model.

Chapter 6. Heat Transfer in Hot Stamping Process of High-Strength Steel
Abstract
Fourier law can be expressed as follows: in the process of heat conduction, the heat through a given section per unit time is proportional to the temperature gradient perpendicular to that section and the corresponding sectional area, but the direction of heat transfer is opposite to the temperature rising direction.

Chapter 8. Hot Stamping Simulation Algorithms of High-Strength Steels
Abstract
Hot stamping of high-strength steels is based on the large plastic deformation of metal, with high nonlinear mechanical characteristics of geometry, physics, and boundary friction.

Chapter 9. Lightweight of Car Body Structure Applied by Hot Stamping Parts
Abstract
Hot stamping parts are highly fit for vehicle structures design and manufacture due to their ultra-high strength and hardness. In what aspect the hot stamping parts are reflected when applied in vehicle lightweight? How can we judge the service performance and proceed with the optimization design? How does it work when the vehicle’s service performance is increased? In this chapter, we will research all the above questions through both simulation method and experiment method.
