摘要
P元素在晶界的偏聚被认为是导致钢回火脆性的一个重要的原因。Mo作为合金元素会减轻钢的回火脆性。然而,通过对晶界处元素的俄歇测定发现,2.25Cr1Mo钢中P与Mo在晶界处存在共偏聚现象。
It has been considered that the segregation of P at grain boundary is one of the important reasons for temper embrittlement of steels. As a salutary alloy element, the addition of Mo can alleviate temper embrittlement of steels. However, observed by Auger electron spectroscope, it were founded that Mo co-segregated with P at grain boundary in 2.25Cr1Mo.
