摘要
Abstract
The air compressor swash plate with double T type QSn7-0.2 copper alloy parts were prepared with different semi-solid extrusion forming processes,the microstructure of as cast and different semi-solid extrusion forming processes were investigated,and the influence of holding time,holding temperature and extrusion speed on the microstructure were investigated,and the microstructure of components in different position was analyzed.The results show that the density,uniformity of microstructure and synergetic deformation of semi-solid extrusion casting are better than the direct conventional casting parts.The best semi-solid extrusion process parameters as follows:the holding temperature,time,extrusion speed is 940 ℃,60 min,and 10 mm/s,respectively.The microstructure of punch head area and the center of the casting are evenly distributed uniform,while the front of the casting is less homogenous.关键词
