利用TEM及HREM研究了9Ni钢中马氏体与渗碳体的取向关系和相界结构观察表明多数马氏体与渗碳体之间满足Bagaryaskii关系,但也有例外观察到一种和已知的三种取向关系不同的情况:(110)θ//(110)α;[111]θ//[111]α棒状渗碳体与马氏体界面上存在台阶.颗粒状渗碳体和马氏体相界间存在失配位错
In the present paper, the orientation relationship and the atomic structure of phase boundary between martensite and cementite have been studied by means of TEM and HREM. An orientation relationship different from Bagaryaskii, Isaichev or Pitsch-Petch rel
