Resum
The interaction of matrix screw dislocations with twin boundaries has been simulated by computer for different h.c.p. models representing a-titanium and magnesium. The atomic structure of the screw core in these two models is appropriate for crystals that slip predominantly on the prism and basal planes, respectively, and this behaviour is summarised in the first part of the paper. Then the movement under three different components of applied strain of the 1/3< 11–0> matrix screw dislocation (...
