The observation by TEM showed that the formationofmartensite in austempering process is preferentially completed through the coherent growth to prior martensite plate.
通过TEM观察表明，等温马氏体形成时，将优先以原马氏体片共格长大的方式进行。

Plenty of twin relationships are determined in the 20%mn steel and there exists the dependence of the formationofmartensite induced by deformation on grain orientations of austenite.
确定了含锰20%的高锰钢中大量的孪晶关系和形变时诱导出的马氏体有明显的取向选择性。

Martensiteformation is covered. The relationships between microstructure and strength, toughness, and ductility is presented in terms of the concepts developed throughout the course.
