摘要
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.
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 relationship has been observed. The interface between stick cementite and martensite contains steps and that between particle cementite and martensite is composed of misfit dislocations.
