本文主要研究了PREP-Ti829+RE(RE=Er,Gd)粉末颗粒的组织形态,测量了粉末颗粒的原始β晶粒尺寸与粉末粒度的关系,并估计了不同粒度粉末的冷却速度。
In this paper, the morphology of the PREP-Ti829 + RE (RE = Er, Gd) powder particles was studied. The relationship between the original β crystal size and the particle size was measured and the cooling rate of powders with different particle sizes was estimated.
