In-Situ Observation of Martensitic Transformation in a Fe–C–Mn–Si Bainitic Steel During Austempering
TL;DR: The martensitic transformation in a Fe-C-Mn-Si bainitic steel was examined by in situ high-temperature laser scanning confocal microscopy (LSCM) and dilatometry as discussed by the authors.
Journal ArticleDOI
Effects of laser beam defocusing on high-strain-rate tensile behavior of press-hardened Zn-coated 22MnB5 steel welds
TL;DR: In this paper, a modified laser weld concavity by beam defocusing can successfully shift the failure location from the fusion zone to the base material, which drastically improves the dynamic loading performance of Zn-coated 22MnB5 laser joints in automotive crash situations.

Adel Saoudi,Mamoun Fellah,Naouel Hezil,Djahida Lerari,Farida Khamouli,L'hadi Atoui,Khaldoun Bachari,Julia Morozova,Aleksei Obrosov,Mohammed Abdul Samad +9 more
TL;DR: In this article, an ANN model was developed to predict tensile and impact properties of a submerged arc helical welded (SAHW) pipeline steel API X70 based upon its chemical composition.
Journal ArticleDOI
The failure mechanism of resistance spot welded third-generation medium-Mn steel during shear-tension loading
TL;DR: In this paper , the failure mechanism of M-Mn spot weld during shear-tension loading was investigated and it was shown that cracks initially propagated in the heat-affected zone, they eventually spread out towards the fusion zone (FZ) resulting in the occurrence of interfacial failure.

The Deformation and Ageing of Mild Steel: III Discussion of Results
TL;DR: In this paper, an attempt is made to explain the observed phenomena in the yielding and ageing of mild steel, described in two previous papers, in the general terms of a grain-boundary theory.

Current issues in recrystallization: a review
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.
Journal ArticleDOI
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).
