| 摘 要： | 使用Gleeble-1500型热模拟机，对D6Acl(30CrNiSiMoV)超高强度钢在奥氏体状态下进行循环预应变淬火，可使马氏体组织得到显著细化，使马氏体板条宽度接近亚纳米量级。研究证实，存在于固相奥氏体中的弹性应变能与塑性变形相配合是使马氏体得到显著细化的重要原因。它为钢的超细化处理提供了新的思路。

| Abstract: | using geeble-1500 thermal analogue test machine,the ultrastrength steel 30CrMnSiMoV was prestrained in austensite state,and then quenched by test.The results show that the elastic strain energy kept in the sample stimulates homogeneous nucleation of martensite while the plastic strain restricts the growth of martensite.If the elastic strain and the plastic strain are matched appropriately,the lath of martensite can be distinctively retined to nanometer scale.The stuely provided the new approach to ultra-fine steels. |
