摘要

铝硅基合金广泛应用于汽车和航空航天工业，而高熵合金则具有许多诱人的特性。在这项研究中，采用了铝钴铬铁镍高熵合金（HEA），通过金属基复合材料的方法来改善铝硅镁合金的性能。金属基复合粉末混合物在 500°C 的温度下用热压机以 50 兆帕的压力烧结。发现 HEA 相分布均匀。通过在 AlSi10Mg 合金中增强 HEA，硬度和抗压强度分别提高了 20% 和 40%。

AlCoCrFeNi HEA reinforced Al–Si–Mg alloy composite through hot-press sintering

Al–Si-based alloys are widely used in the automobile and aerospace industries, whereas high entropy alloys have emerged with many attractive properties. In this study, AlCoCrFeNi high entropy alloy (HEA) is employed to improve the properties of AlSi10Mg alloy through a metal matrix composite approach. Metal matrix composite powder mixture was sintered at 500°C using a hot press at a pressure of 50 MPa. HEA phase was found to be distributed uniformly. An increase of 20 and 40% in hardness and compressive strength were observed by reinforcing HEA in AlSi10Mg alloy.
