摘要
研究2.25Cr-1Mo-0.25V钢奥氏体晶粒随加热温度的变化规律和组织遗传对晶粒度的影响。结果表明:温度超过1 000℃时,晶粒度过度长大;组织遗传是形成粗晶的原因之一。
This paper researches tile variation rule nf 2.25Cr-1 Mo-0.25V steel austenite grain along heating tem- perature and the influence of structure heredity on grain size. The results show that the grain size grows up excessively when temperature is over 1000℃ and the structure heredity is one of reasons lo t＇orm coarse grain.
