Influence of surface preparation method on retained austenite quantification
L.A. Pinto,D. Pérez Escobar,O.S.H. Santos,Natalia Isabel de Azevedo Lopes,J.R.G. Carneiro,R. Ribeiro-Andrade +5 more
TL;DR: In this paper, X-ray diffraction and electron backscatter diffraction (EBSD) methods were used to identify and quantify retained austenite fraction in 15XX class steel, in addition to verifying the best metallographic preparation methodology.

Precipitation behaviour and strengthening mechanisms of V-bearing 1800 MPa grade hot-stamping steel
Zhuo Yuan Cheng,Shuize Wang,Jinyue Liu,Ruoqing Wu,Junheng Gao,Honghui Wu,Tianyi Li,Guilin Wu,Xinping Mao +8 more
TL;DR: In this paper , the effects of V content on the microstructure and mechanical properties of 1800 MPa grade hot-stamping steel are systematically studied, showing that the tensile strength decreases slightly with increasing V content, as V consumes C in the martensite matrix by forming carbides and promoting precipitate coarsening.

Influence of in situ postweld heat treatment on microstructure and failure behavior of dual-phase steel resistance spot weld
TL;DR: In this article, the effect of in situ postweld heat treatment (PWHT) on microstructure, tensile shear properties, failure mode, and hardness distribution of resistance spot weld of dual-phase (DP590) steel was investigated in terms of peak load and failure energy.

Roger D. Doherty,D.A. Hughes,F.J. Humphreys,John J. Jonas,D. Juul Jensen,Michael E. Kassner,Wayne E. King,Terry R. McNelley,H.J. McQueen,Anthony D. Rollett +9 more
TL;DR: The current understanding of the fundamentals of recrystallization is summarized in this paper, which includes understanding the as-deformed state, nucleation and growth, the development of misorientation during deformation, continuous, dynamic, and geometric dynamic recystallization, particle effects, and texture.

Dynamic and post-dynamic recrystallization under hot, cold and severe plastic deformation conditions
TL;DR: In this paper, the evolution of the new microstructures produced by two types of dynamic recrystallization is reviewed, including those brought about by severe plastic deformation (SPD).
