The formation of twin structure depends on the slip of stacking fault for nucleating and extending.
孪晶结构的形成依靠堆垛层错的滑移运动而形核和扩展。

Both of the formation possibility of the coupled twins and single twin induced by impurity atom are 50%.
杂质原子诱发成对孪晶及单孪晶的的可能性各为50%。

Plenty of twin relationships are determined in the 20%mn steel and there exists the dependence of the formation of martensite induced by deformation on grain orientations of austenite.
