Twin boundaries (TBs) are ubiquitous interfaces with specific structure in metallic materials.
They possess special interactions with dislocations and the fatigue cracking behaviors are …

Catastrophic accidents caused by fatigue failures often occur in engineering structures.
Thus, a fundamental understanding of cyclic-deformation and fatigue-failure mechanisms is …

The rapid development of automotive industry results in a series of increasingly serious
problems such as energy consumption and environmental pollution, so that developing the …

Abstract High Entropy Alloys (HEAs) are a new class of multi-component alloys with
excellent tensile strength-ductility combination. Their yield strength levels, however, are still …

A twinning-induced plasticity (TWIP) steel was processed by warm rolling with different
reduction ratios to elevate yield strength while maintaining considerable ductility. To …

Enhancing strength-ductility synergy of materials has always been a hot but difficult topic in
material science, for most structural materials, steels in particular, it is inevitable to sacrifice …

Multi-principal element alloys (MPEAs) of low stacking fault energies (SFEs) often exhibit
outstanding damage tolerance. In contrast to the well-understood monotonic deformation …

Compared to stress controlled high-cycle fatigue, enhancing strain controlled low-cycle
fatigue (LCF) properties of material is much more difficult and less reported. In this study, we …

Cyclic deformation behavior and damage mechanisms of Cu-Mn alloys with high stacking
fault energies (SFE) were systemically investigated at constant total strain amplitude in the …

A multi-phase non-equiatomic FeCrNiMnCo high entropy alloy (HEA) was fabricated using
vacuum induction melting. Thermo-mechanical treatments consisting of cold rolling and …
