摘要：
The rotation associated with a tilt wall is derived from elastic displacement fields and shown to agree with the tilt deduced from Burgers circuits. Transmission of a dislocation through a boundary results in a disconnection forming at the boundary and different mechanisms are proposed for the removal of a disconnection from low- and high-angle boundaries. The results have implications for the formation of kink bands, deformation bands, and compound twins as well as for the appropriate rotation matrix to be used in predicting martensite habit planes.
