研究IN783合金显微组织及析出相,测定偏析相的初熔点温度。通过对不同温度、时间均匀化处理后合金试样中Nb元素的偏析程度以及β相的细化情况分析,确定IN783合金均匀化处理工艺。

The segregative phases and it’s solution temperature in alloy IN783 were investigated.A optimum homogenization treatment system was proposed based on the study of microstructures and the segregative phases in the specimen after a number of heat treatments.
