Abstract：
CoCrFeMnNi/6061 Al composites were prepared by spark plasma sintering. SEM, XRD and nanoindentation were used to analyze the interface morphology and microscale mechanical properties. The results show that the reaction interfacial layer with a thickness of about 20 μm is formed between the matrix and the reinforced particles, and BCC solid solution phase is generated. The change trend of elastic modulus and hardness in microscale is the same. The micro-nano mechanical properties of the interfacial layer are higher than those of the matrix and the reinforced particles. The interfacial layer plays an important role in improving the mechanical properties of the composites.
