The present study investigated the microstructure and mechanical properties of as-hot-rolled Fe 64 (CoCrNi) 36 (at.%) ferrous medium-entropy alloys (Fe-MEAs), demonstrating a remarkable 142% enhancement in yield strength (YS) and a superior uniform elongation of 43.0%, in comparison to the co...
Realizing improved strength–ductility synergy in eutectic alloys acting as in situ composite materials remains a challenge in conventional eutectic systems, which is why eutectic high-entropy alloys (EHEAs), a newly-emerging multi-principal-element eutectic category, may offer wider in situ ...

Strength–plasticity synergy enabled by lattice distortion In order to develop an alloy with both large lattice distortion and a stable lattice structure, we took into consideration the influence of large atomic size differences and electronic property variations. These factors contribute to the formation...
A dual-phase (DP) Ni–66.7%Co alloy with an average grain size of 16 nm was fabricated by electrodeposition. It exhibited an ultimate tensile strength of 1800–2080 MPa, together with an elongation to failure of 10–15% at room temperature. The remarkable ductility of this DP alloy with ...

On the one hand, the high tensile yield strength (TYS) of 343 MPa was obtained by extrusion at 250 & DEG;C mainly due to the combined effects of profuse nano-precipitation phase, grain refinement, texture strengthening and high-density dislocation; On the other hand, the excellent elongation...
A combination of 1 to 1.2 GPa yield strength (21.3 % increase) with a total elongation of 20 to 10 % was achieved. The chosen methodology was efficient in the design of a novel MPEA with an improved strength-ductility synergy.doi:10.1016/j.matdes.2020.109315Fabian Kies...
introduced phase heterogeneity in Fe50Mn30Co10Cr10 via the transformation-induced plasticity (TRIP) mechanism, leading to the substantially enhanced strength-ductility synergy with the tensile elongation >70% [9]. Pan et al. constructed a heterogeneous gradient dislocation cell structure (GDS) in Al...
