本文采用30CrMnSiNi2A钢在等屈服强度条件下对比不同显微组织与Cd脆的敏感性。结果表明,回火马氏体(M_T)的Cd脆敏感性最大,(M_T+B_L)混合组织次之,下贝氏体(B_L)最小。
The effect of different microstructures of steel 30CrMnSiNi2A on thesusceptibility of cadmium embrittlement has been studied and compared under theunique yield strength level. The results show that the tempered martensite exhibitsthe maximum susceptibility to cadmium embrittlement, while the lower bainite showsthe minimum susceptibility. The mixed microstructure of the above two has asusceptibility in between.
