The Ni61Fe10Cr10Al17Mo2 high entropy alloys (HEAs) with low density have been developed great potentials for applications. forging process is one of the important methods fabricating components. Accordingly, study deformation behavior HEAs essence in processing and molding this material using industry. Moreover, there are multiple phases hierarchical structures as-cast alloys, face-centered cubic (FCC) phase as matrix accompanied hard body-centered (BCC) B2 phase. Here, hot behaviors...
The eutectic high-entropy alloys have shown promising mechanical behaviours while their softening at elevated temperatures is still a challenge. Generally, the boundaries are weak parts to be strengthened with increased in alloys. Here, we found that minor addition of boron Ni30Co30Cr10Fe10Al18W2 alloy can significantly strengthen FCC grain and FCC/B2 phase temperatures. A remarkable tensile yield strength over 581 MPa elongation 71% 800 °C achieved addition, corresponding 45% increase 129%...
Dual-phase high-entropy alloys with excellent room temperature and high-temperature properties have been widely studied as potential structural materials. However, interface weakening causes its performance to decline at higher temperatures, severely limiting further development. In this study, a series of Al17Cr10Fe36Ni36Mo1Hfx (x = 0, 0.03, 0.15, 0.3, 0.5, 0.8 at%) were prepared study the effect Hf content on microstructure mechanical matrix alloy. The results indicate that addition Hf,...

Multi-component alloys with good mechanical properties and casting liquidity have become a hotspot in the materials field. Typically, addition of minor metal elements plays vital role strengthening properties. However, doping metalloid such as Si into multi-component is also an effective method to enhance In present study, effect (0 ~ 4 at.%) on microstructure was investigated within both as-cast thermal treatment states. state, all exhibited dendrites interdendrites structure. The fine...
The cost-effective high-entropy Ni61Fe10Cr10Al17Mo2 alloys with low density have been developed great potentials for applications. forging process will be one of the important methods fabricating components. Accordingly, hot deformation behavior should explored. Moreover, there are multiple phases hierarchical structures in as-cast alloys, a FCC phase as matrix accompanied hard B2 phase. Here, behaviors homogenized alloy were investigated strain rates ranging from 0.001 s-1 to 1.0 and...
