INHOMOGENEOUS ORDERING DUE TO EXCESS VACANCIES: AN ORDER-STRENGTHENING MECHANISM

Abstract

It is noted that quenched-in excess vacancies decay more rapidly in th vicinity of dislocations and this gives rise to a low r long-range ordering ra n r di locations. It is shown that in partially ordered system , dislocations will be locked-in by an order gradient and thatA YIELD POINT IS TO BE EXPECTED. The magnitude of the effect is calculated for beta brass on the basis of quasi-chemical binding and a yield stress comparable with the observed is obtained. It is also sho n t at this model of inhomogeneous ordering yields a simple explanation of an anomalous r sistivity effect observed in Cu3Au. (Author)
