摘要：

In this paper dislocations and twins formed under Vickers indentation of different planes of CdWO4 crystals are studied. It has been found that on (010) and (100) faces fresh dislocations run along [001] from an imprint of Vickers pyramid. On (001) twins with (010) twinning plane induced by indenter propagate along [100]. Twins with {011} twin planes are induced by indentation on (100). Possible dislocation dissociation reactions and role of the resulting partial dislocations in twinning during microindentaion in cadmium tungstate are discussed.
