根据TiAl基合金片层组织的准三维金相形态准确地判断出其初生相类型。结果表明,具有不同片层取向的晶粒在Ti-50Al-5Nb合金定向凝固过程中其初生相均为β相。
According to the quasi-three-dimensional metallographic morphology of the TiAl-based lamellar structure, the type of primary phase is accurately determined. The results show that the grains with different lamellar orientation are β phase in the primary phase during the directional solidification of Ti-50Al-5Nb alloy.
