摘要

An CoCrFeMnNi high-entropy alloy (HEA) particles reinforced 2024Al alloy composite was prepared by spark plasma sintering (SPS). There is an interdiffusion (ID) layer between the HEA particle and the matrix. The composition and micromechanical properties of the diffusion layer were investigated by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), electron probe and nanoindentation. The unique element distribution in the diffusion layer and the obvious creep phenomenon are related to the sintering mode. The hardness of the composite is increased 63.7%, which was attributed to particle reinforcement and the relative low content of sintering defects in the matrix.
