Nucleation and Growth of Defects in Heavy-Ion and Electron-Bombarded Metals. Final Report for the Period Ending February 29, 1980

摘要

He preinjection was found to be essential in nucleating voids in high-purity Al. Interstitial pickup in high-purity V was found to be important even under good vacuum (10 exp -6 to 10 exp -7 torr). Voids were found to form in V down to 200 exp 0 C. A model was tested against rdiation disordering/ordering in Cu sub 3 Au. Disordering in CuPd was studied. A small negative heavy ion source (SNICS) was developed for the tandem accelerator. (ERA citation 08:032016)
