Factors Affecting the Inclusion Potency for Acicular Ferrite Nucleation in High-Strength Steel Welds
TL;DR: In this paper, three factors affecting the ferrite nucleation potency of inclusions were evaluated: the Baker-nutting (B-N) orientation relationship between ferrite and the inclusion, the formation of an Mn-depleted zone (MDZ) near the inclusion; and the strain energy around the inclusion.
Journal ArticleDOI
Formation of a high-cycle fatigue fracture surface and a crack growth mechanism of ultrafine-grained copper with different stages of microstructural evolution
TL;DR: In this paper, a quantitative model describing the crack growth mechanism was developed by considering the reversible plastic zone size and the microstructural factors, which corresponded to the transition from planar to granular fracture surface and from granular to striated fracture surface.
Journal ArticleDOI
Crystal plasticity finite element analysis of ferritic stainless steel for sheet formability prediction
TL;DR: In this paper, a virtual microstructure crystal plasticity finite element model, or a representative volume element (RVE), was developed, in which the behavior of grains was governed by a rate-dependent viscoplastic model.
Journal ArticleDOI
Deformation mechanisms and texture evolution in high entropy alloy during cold rolling
Lalit Kaushik,Min-Seong Kim,Jaiveer Singh,Joo-Hee Kang,Yoon-Uk Heo,Jin-Yoo Suh,Shi-Hoon Choi +6 more
TL;DR: In this paper, a CoCrFeMnNi high entropy alloy (HEA) was subjected to thickness reductions of 20, 40, and 60% during cold rolling in order to thoroughly investigate the evolutions of both the microstructure and the deformation texture.
Journal ArticleDOI
Multi-phase refining of an AlCoCrFeNi high entropy alloy by hot compression
TL;DR: In this paper, the microstructural development of AlCoCrFeNi high entropy alloys annealed and compressed at 1100°C was investigated, and it was shown that duplex microstructures consisting of fine equiaxed fcc and bcc phases, whose average grain sizes drastically decreased to 1.54 and 1.97μm, respectively.
