摘要
研究了静磁场（０－１．２ Ｔ）对 ３２ＣｒＭｎＮｂＶ淬透性及耐蚀性能的影响实验中发现，在连续冷却过程中加磁场，可以使铁素体转变的 ＣＣＴ曲线左移，淬透性下降；在奥氏体化过程加磁场，会降低奥氏体的稳定性，造成冷却过程中 ＣＣＴ曲线的左移，而且左移的趋势更明显当淬火时所加磁场的强度增加到１．２Ｔ，马氏体组织明显细化．此外，磁场下淬火可以提高马氏体的耐蚀性，随着外磁场的增加，腐蚀速率下降．
The effect of static magnetic field (0-1.2 T) on the hardenability and the corrosion- resistant of the 32CrMnNbV alloy was studied. It is found that the continuously cooling under magnetic field induces the CCT curve of the ferritic transformation moves to left and the hardenability is reduced, and the austenizing under magnetic field makes the stability of austenite drops down and the CCT curve shifts to much more left than quenching under magnetic field. In addition, quenching under magnetic field increases the corrosion-resistant of martensite, and the corrosion rate is reduced with increasing magnetic field.
