Abstract
The paper discusses the formation of unconforming dislocations at antiphase boundaries APB. The stress due to the interaction with superdislocations is estimated, and this stress is evaluated as a function of the size of the antiphase domain. It is shown that a gliding superdislocation cutting through APB of type 1/2 <111> {110} in CuZn and through cubic APB of (α+Β) type in AuCu3 facilitates passage of the superdislocation, while the converse applies for cubic APB ofΒ type in AuCu3. There is only slight resistance to the motion of the superdislocation on account of octahedral APB in AuCu3.
