We proposed an equation of Langevin type to describe the interface evolution in crystals under nonequilibrium conditions(such as in Cu-Fe or Cu-Co system upon ball miling). The scaling property (H) of this equation is in good agreement with the Monte Carlo simulations decribed by Bellon and Averback. In this equation the volume dchsion and intedece diffusion are all important and this is consistent with some experimental results.

The A/D type twin boundary in a Cu-Zn-Al shape memory alloy appears curved under TEM and shows impularly sermted steps under HREM Crystallogmphic analysis shows that the macroscopic curve results hem non-selfaccommodation of the boundary, the deviation from exact twin orientation and a pwtrential orientation for lower boundary enerpy.
