AlSiTiCrNiCu high-entropy alloy particles were used as the reinforcement to reinforce the aluminum alloy. Then the effect of the volume fraction of high-entropy alloy and the sintering temperature on the thermal conductivity of the composites was investigated. The result shows that the thermal conductivity of (AlSiTiCrNiCu)p/6061Al composites decreases with the increase of the volume fraction of AlSiTiCrNiCu particles, and the thermal conductivity of (AlSiTiCrNiCu)p/6061Al composites with reinforcement of 20% volume fraction is 61.6 W?(m?K)-1, which is decreased by 52% compared to that of the matrix 6061Al alloy. When the reinforcement volume fraction is 10%, the thermal conductivity of the composites decreases with increasing the sintering temperature, and the thermal conductivity of the composites is 65.80 W?(m?K)-1 when the sintering temperature is 540℃.
