The purpose of this study is to realize a recycling method for aluminum chips in solidification molding. In this method, aluminum chips are heat treated under different conditions, SPS is applied, and then HPS processing is performed. In this experiment, HPS processing was performed on heat-treated specimens under several conditions, and HPS processing was performed after SPS on the same specimens. The tensile strength and elongation were determined by tensile testing, and the hardness was determined by Vickers hardness testing, to clarify the effects of heat treatment conditions, SPS, and HPS processing. The microstructures were observed, and the theoretical values calculated by the theoretical equation were compared with the experimental values obtained by Vickers hardness testing．
