论述了镍基625合金的析出转变行为及其影响因素,从合金的凝固行为、热处理制度、化学成分等方面进行讨论。析出相主要由合金元素的扩散、偏析所主导,并且随热处理时间与温度的不同而发生转变。
The precipitation transformation behavior of Ni-based 625 alloy and its influencing factors were discussed. The solidification behavior, heat treatment system and chemical composition of the alloy were discussed. The precipitated phase is mainly dominated by the diffusion and segregation of alloying elements, and changes with the time and temperature of heat treatment.
