Microstructure and homogenization process of as-cast GH4169D alloy for novel turbine diskKai Chen,Shu-yuan Rui,Fa Wang,Jian-xin Dong,Zhi-hao Yao摘 要:To investigate the microstructure, segregation, and suitable homogenization process of as-cast GH4169 D alloy, the microstructure, elements segregation, and precipitates of cast GH4169D ingots prepared......
homogenization treatment were investigated. The as-cast alloy was found to be composed of dendritic primaryα-Mg matrix, α-Mg +W(Mg3Zn3Gd2) eutectic along grain boundaries, and icosahedral quasicrystalline I(Mg3Zn6Gd) phase within α-Mg matrix. During homogenization process, α-Mg +W(Mg3Zn3Gd2) eutectic and I phase gradually dissolved into a-Mg matrix, while some rod-like rare earth hydrides(GdH2)formed......
