摘　　要：合金含量、精铸工艺参数(出炉温度、浇铸温度、模壳预热温度、保温时间、冷却方式)对叶片脆性问题存在一定的影响。为了消除静叶片的脆性断裂,采用正交试验对脆性问题进行了研究。结果表明,合金含量及工艺参数的交互作用对叶片脆性影响显著。The alloy component and the process parameters of the precision casting （including the exit temperature from furnace, pouring temperature, mould preheating temperature, holding time, cooling form） have a certain influence on the problem of the blade brittles. In order to eliminate the brittle fracture of the stator blade, using the orthogonal experiment, the brittle problem of the stator blade was studied.The results show that the corrdlation between the alloy component and the process parameters has notable influence on the brittle of the stator blade.
