TiB2/AlFeNiCoCr high-entropy-alloy-matrix composites were fabricated by spark plasma sintering. Effects of SPS process on microstructure and mechanical properties of 0.5 vol.% TiB2/AlFeNiCoCr composites were studied using X-ray diffraction, density testing, scanning electron microscopy, mechanical property testing. It is shown that increasing of sintering temperature and pressure can improve the relative density and compressive properties of 5 vol. %TiB2/AlCoCrFeNi composites. During the spark plasma sintering, there is phase evolution in the composites. The 5 vol. % TiB2/AlCoCrFeNi composite after sintering at 1200 °C and 30 ~ 45 MPa is composed of phases BCC, B2, FCC, σ and TiB2.
