非共格界面

进一步增加调制周期，两调制层之间产生非共格界面，破坏了薄膜中的交变应力场，薄膜的硬度和弹性模量也随之降低。

Further increasing modulation period leads to the emerge of incoherent interface and the destroy of alternating stress field , accompanied by the decreased mechanical properties .

非共格界面为位错的攀移运动提供了有效的扩散通道，Cu/Nb和Ag/Fe多层膜的蠕变抗力随周期减小而减小。

For fcc / bcc Cu / Nb and Ag / Fe multilayers , the incoherent interfaces can provide effective climb diffusion paths and thus the creep resistance decreases with decreasing periodicity .

非共格孪晶界面位移矢量的测定与分析

Determination and analysis of displacement vectors at the incoherent twin boundaries

此外孪晶移动到边界处会受到阻碍，形成非共格的孪晶界面。

In addition , the twins crystals moving to boundary will be hindered , and form the incoherent twin .
