A study was made of the statics and dynamics, of vacancies and self-interstitials in model -phase lattices, by means of computer simulation techniques. These started from the development of a suitable interatomic potential, and led finally to an evaluation of the anisotropy of diffusion via vacancies or self-interstitials. Experimental results on self-diffusion in monocrystals of -Ti were analyzed within the framework of the calculated diffusion constants for a vacancy mechanism. The occurrence of predominantly basal self-interstitial diffusion was predicted.
