High strength steels are commonly used in the automotive industry to reduce mass and improve structural performance. This chapter discusses the history of steel in the manufacture of automobiles, the types of steels currently being used and the new advances in the types of steels that can be used for lightweighting automotive structures. The chapter also reviews the manufacturing and forming aspects of these steels along with some design considerations for the selection of these materials.read more

A strategy for synthetic microstructure generation and crystal plasticity parameter calibration of fine-grain-structured dual-phase steel
Wenqi Liu,Wenqi Liu,Junhe Lian,Junhe Lian,Nikolaos Aravas,Nikolaos Aravas,Sebastian Münstermann +6 more
TL;DR: In this paper, an assessment criterion is proposed to quantitatively examine the representativeness of synthetic microstructure models in terms of the refined microstructural features including phase fraction, grain size, grain shape, and texture for each phase of the steel.

Investigations Into the Influence of Weld Zone on Formability of Fiber Laser-Welded Advanced High Strength Steel
TL;DR: In this article, two different dual phase steel grades DP980 and DP600, and IFHS steel sheets were laser welded by a 2-kW fiber laser, and the weld quality of these three different LWBs was assessed with the help of microstructure, micro-hardness and transverse tensile tests.

Hydrogen embrittlement of an automotive 1700 MPa martensitic advanced high-strength steel
Jeffrey Venezuela,Fang Yan Lim,Li Liu,Sonia James,Qingjun Zhou,Ruth Knibbe,Ming-Xing Zhang,Huixing Li,Futao Dong,Futao Dong,Matthew S. Dargusch,Andrej Atrens +11 more
TL;DR: In this paper, the influence of hydrogen on a 1700MPa martensitic advanced high-strength steel was investigated and compared with similar steels, showing that the hydrogen influence manifested as a reduction of ductility and the occurrence of shear fracture.
