GH105合金铸锭元素偏析和均匀化工艺
Microsegregation and homogenization of GH105 superalloy ingots
摘要
Abstract
Microsegregation and homogenization of superalloy GH105 ingots were studied by optical microscope, scanning electron microscopy and EDAX. The results show that the severe segregated elements are Ti and Mo, and the segregation degree can be reduced by a two-stage heat-treatment of homogenization. The homogenization process can be effectively predicted by the homogenizing equation, which agrees with experimental results as a whole, while there are some errors between experimental results and those predicted by the residual segregation parameter model.关键词
