A novel high-entropy alloys (HEAs)-joining strategy was proposed by brazing Al0·3CoCrFeNi substrates at 1573 K in vacuum using a pure niobium interlayer. The brazed Al0·3CoCrFeNi joints have a eutectic structure of face-centered-cubic (FCC) and C14 Laves phases, exhibiting excellent strength-ductility synergy at both room and liquid-nitrogen temperatures.

纯铌Al0·3CoCrFeNi高熵合金的原位共晶反应键合

提出了一种新的高熵合金(HEAs)连接策略,方法是使用纯铌夹层在真空中在 1573 K下钎焊 Al 0·3 CoCrFeNi 基板。钎焊的 Al 0·3 CoCrFeNi 接头具有面心立方 (FCC) 和 C14 Laves 相的共晶结构,在室温和液氮温度下均表现出优异的强度-塑性协同作用。
