搅拌摩擦加工制备FeCoNiCrMn高熵合金增强铝基复合材料的组织与力学性能研究
Microstructure and Mechanical Properties of FeCoNiCrMn High Entropy Alloy Reinforced Aluminum Matrix Composites Prepared by Friction Stir Processing
摘要
Abstract
High entropy alloy (HEA) particles are dispersed into 2024 aluminum alloy matrix by multi-pass friction stir processing (FSP) process to prepare HEA/Al composites. The effects of FSP passes on the macro morphology, microstructure and mechanical properties of the composites are studied. The microstructure observation shows that increasing FSP passes contributes to the uniform distribution of high entropy alloy particles and grain refinement. The test results of mechanical properties show that with the increase of FSP passes, the microhardness value of FSPed composites is significantly improved, the distribution is more uniform, and the strength and plasticity are also improved. The microhardness, strength and plasticity of five-pass FSPed composites reach 138 HV, 597 MPa and 5.1％, respectively.关键词
