摘　　要：以细晶铸造高温合金K4169为研究对象,对晶粒细化情况和细化晶粒后高温合金加工性能的变化情况分别进行研究,重点通过铣削力测试和加工后表面粗糙度测试实验,分析晶粒大小不同的高温合金试样加工性能变化,以此说明晶粒细化的实际意义。最后分析了加工性能变化的原因,并对铣削力、表面粗糙度与晶粒大小的关系进行了曲线拟合。The project is to study the machinability of fine grain casting Superalloys .K4169.The grain of sample and the change of working properties of Superalloys after grain refinement were studied.In order to show the reality of grain refinement, two things have been done to test working properties of different grain of sample.One is testing the force of milling, the other is testing the roughness of the milling surface.In the end ,the reason of changing of machinability was been analyzed, curve fitting was done to analyze the relationship about the force of milling and roughness with grainsize.
