摘　　要：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。Precipitation behavior of nickel-base alloy 625 and the related factors are reviewed,including the discussion of the solidification behavior,heat treatment regime and the chemical composition. The precipitated phases are predominated by segregation and diffusion of the alloying elements,while the phase transforms to the time and temperature of heat treatment.
