secondary twin

In the Cr_7C_3 , the { 013 } growth twin was discovered by the electron diffraction patterns and the secondary twin might be possibly found .

从电子衍射花样上发现了Cr7C3相中存在{013}生长孪晶，并可能存在着二次孪晶。

The intersecting of two deformation twin plates also brought about the formation of secondary austenite twin , but its formation mechanism may be different from that for the martensite intersecting . The detail is still under analysis .

在Al3钢中两个变形孪晶也同样在交叉处形成了二次奥氏体相，但它的形成机制与马氏体板条相交叉的机制不同，形成机理仍有待进一步研究。

The twinned Al_4C_3 phases exist in hot-dip aluminized steel . In hexagonal system , there is 180 ° secondary rotation twin with ( 003 ) as twinning plane and direction as twinning axis .

发现Al4C3相以孪晶方式存在，六方晶系中存在以（003）面为孪晶面，以[001]方向为旋转轴的180°二次旋转孪晶。
