ABSTRACT
Dislocation behavior in twinned crystals has been studied by means of x-ray diffraction topography. Dislocation slip motion is interrupted by the growth twin boundary and new dislocations are generated from the boundary. Near the boundary, straight dislocations with Burgers vectors parallel to the https://www.w3.org/1998/Math/MathML"> < 11 2 ¯ > https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429070914/679f2623-d509-4a65-a488-93e3a3b19d40/content/eq1328.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> directions and perfect screw dislocations are observed. Dislocation interaction with the twin boundary is discussed.
