摘要
采用悬浮浇铸工艺并控制冷却速度成功地得到了钢颗粒增强纯铜基铸造复合材料。研究表明，钢颗粒与纯铜基体结合良好，钢颗粒没有固溶于纯铜基体，没有造成铁污染，也没有过度扩散，其电阻率为２．１３２×１０^（－２）μΩ·ｍ。
Steel grain-reinforced pure copper cast composite was gotten successfully by suspension casting process and controlling the cooling rate. The results showed that interface grain and pure copper matrix combined well,and the steel grain did not dissolve into copper matrix. There were no pollution of iron element and over diffusion after adding steel grain and the conductivity was as high as 81 %IACS.
