摘要 采用放电等离子烧结制备了AlCoCrFeNiT_i(0.5)高熵合金颗粒含量(体积分数)分别为10%、20%、30%的AlCoCrFeNiTi_(0.5)/Al复合材料。研究了AlCoCrFeNiTi_(0.5)颗粒含量对铝基复合材料力学性能以及微观组织的影响。结果表明,增强体含量低于20%可以同时提高复合材料的室温强度和塑性。当增强体含量为20%时,相比于未增强的试样,抗拉强度和伸长率分别提高90.1%和52%,抗压强度提高76.2%,并仍保持塑性压缩特征。复合材料强度和塑性的提高是由于增强体和基体之间形成了稳定的界面。当增强体含量为30%时,复合材料塑性显著下降,这是由于过多的界面相导致基体损伤。 Al-based matrix composites(AMCs)reinforced with AlCoCrFeNiTi0.5high-entropy alloy particles(HEAp)of 10%,20%,30%in volume fraction,respectively,were consolidated by spark plasma sintering.Influences of HEAp content on room-temperature compressive and tensile properties as well as microstructures were identified.The AMCs reinforced with HEAp less than 20% exhibit win-win of strength and ductility.With HEAp of 20%,the tensile strength and elongation,compressive strength of the composites are increased by 90.1% and 52%,76.2%,compared with those of the composites with absence of HEAp,and still keep the plastic compression characteristics,which are attributed to the better interfacial compatibility between the Al matrix and HEAp.Excess addition of HEAp up to 30%is detrimental to the composites because of overabundance interphase leading to the matrix damage.
