摘要
通过Jmat-Pro软件模拟了6种化学元素不同含量时12%Cr转子钢中铁素体的含量,研究了这6种化学元素对该转子钢中铁素体含量的影响规律。结果表明:C、N和Co元素能有效抑制铁素体的形成,Cr和W元素能促进铁素体的形成。
Based on the Jmat-Pro software,the influence of six chemical elements( C、N、Cr、W 、B and Co) on the ferrite content of 12%Cr rotor steel has been studied. The results show that C,N and Co elements can effectively restrain the formation of ferrite,Cr and W elements can promote the formation of ferrite.
