A single-phase bimodal grain structure is considered to develop a physical model to quantify
hetero-deformation induced (HDI) strengthening at the yield point, which cannot be simply …

Heterogeneous structures (HS) have been reported to overcome the longstanding challenge
of the trade-off between strength and ductility in metallic materials. The deformation …

Low yield strength is the bottleneck of the face-centered cubic-structured high-entropy alloys
(HEAs). Here, the strategy of hetero-deformation-induced (HDI) plasticity is applied by …

Heterogeneous microstructure alloys provide a possibility for the combination of strength
and ductility. As a typical heterogeneous microstructure, partially recrystallized …

Abstract The combined Monte Carlo and Molecular Dynamics simulations were employed to
explore the influence of elemental segregation at grain boundaries (GBs) on the mechanical …

High density alloys with enhanced deformability and strength are urgently required in
energy, military and nuclear industries, etc. In this work, we present a new kind of …

Optimization of the plastic deformation mechanism by reducing the stacking fault energy
(SFE) of alloys through precipitation is a promising method to improve the strength–plasticity …

The kinematic and isotropic hardening behavior was investigated for high and medium
entropy alloys with a single-phase face-centered cubic (FCC) structure. The cross-slip …

Abstract A novel (CoCrNi) 93.5 Al 3 Ti 3 C 0.5 medium-entropy alloy was designed, in this
work, based on the equiatomic surplus-ductility carrier to achieve multi-coupling …

The deformation responses of NiCoCrFe high-entropy alloy (HEA) under quasi-static (1×
10− 4-1× 10− 1/s) and dynamic (1,000–6,000/s) tension were investigated. A good …
