The Study of Point Defects in CsCl Ordered Alloys and Other Intermetallic Compounds.
Abstract
Simultaneous radioactive trace diffusion studies of various isotopes of both species in two intermetallic compounds, AuZn and FeCo, were completed. In the former, correlation effects were also analyzed and in the latter, the isotope effect was measured. In the ordered region of FeCo and in the AuZn (also ordered) alloys, the agreement between observations and the theoretical six-atom-vacancy jump mechanism lends strong support to this model. An analysis of line and plane defects produced in situ with the field ion microscope was made and the application of a computer simulation technique was completed. The kinetics of the stabilization of the low temperature product phase following the beta to beta double prime transformation in equiatomic AuCd were successfully accounted for in terms of the annealing out of point defects introduced by the movement of the transformation interface on cooling.
