摘要：
Based on the observation of antiphase-boundary (APE) tubes connected to mixed superdislocations in NI,AI, the hypothesis that APE tubes are trailed behind moving kinks is explored. Evidence is given to show that APE tubes originate in particular at the junction between a kink and a Kear-Wilsdorf lock. The mechanism proposed here for the formation of APE tubes involves the local relaxation by short-range athermal climb motion of the connecting jog; once this is achieved, a straight APE tube is trailed conservatively by the moving kink.
