摘要
以5083铝合金为基体,以FeCoNiCrMn高熵合金颗粒为增强相,通过搅拌摩擦加工技术制备了颗粒增强铝基复合材料,研究了加工道次对复合材料微观组织和显微硬度的影响。研究结果表明:增加加工道次可以使得FeCoNiCrMn高熵合金颗粒在基体中分散更加均匀,显微硬度结果显示添加FeCoNiCrMn高熵合金颗粒后复合材料硬度得到大幅度提升,且5道次加工后的显微硬度最高。
Using 5083 aluminum alloy as the matrix and FeCoNiCrMn high-entropy alloy particles as the reinforcing phase,particle-reinforced aluminum-based composites were prepared by friction stir processing.The effects of processing passes on the microstructure and microhardness of the composites were studied.The research results show that increasing the number of processing passes can make FeCoNiCrMn high-entropy alloy particles more uniformly dispersed in the matrix,and the microhardness results show that the hardness is greatly improved after adding FeCoNiCrMn high-entropy alloy particles,and the microhardness after 5 passes.
