一种FeNi基共晶中熵合金

By adding inexpensive Nb and Ti elements to FeNi-based eutectic medium-entropy alloys, a eutectic structure of Laves phase, BCC phase, and FCC phase is formed, which solves the problem of insufficient strength in existing low-cost eutectic medium-entropy alloys and realizes a medium-entropy alloy with high strength and high toughness, which has good potential for engineering applications.
