摘要: 本文利用光学金相、X射线衍射及透射电镜研究,发现高锰无磁钢具有两种不同形态的板条组织和ε马氏体的扭折形态。固溶淬火形成的断续状短板条及形变诱发形成的细长板条都是由ε马氏体和fcc孪晶所组成,讨论了形成机理。晶体学分析表明,fcc孪晶界两侧的ε马氏体成扭析形态,是因为孪晶界两侧的基体位向不同所致,扭折部分为hcp孪晶。
关键词 ε马氏体fcc孪晶板条组织扭折    
Abstract:Two lath structures and the kinked ε martensite were observed in thehigh manganese non-magnetic steel. Both the short non-continuous lath formed byquenching and the long thin straight lath induced by plastic defomation are com-posed of ε martensite and fcc twin. The transformation mechanism was discussed.The crystallographic analysis indicates that the ε martensite at both sides of thefcc twin boundary is of kinked morphology owing to the orientation of their ma-trixes differed from each other. The kinked region is hcp twin.
Key wordsmartensite    fcc twin    lath structure    kink
