Abstract
The cubic A-15-type structure of chromium has been obtained by evaporating chromium at 673 K in the presence of ammonia plasma. The presence of N, NH, C, and CH species in the films suggests that the cubic A-15 structure is stabilized by these species. Deposition at Ts >773 K, or by annealing the as-deposited films at temperatures >773 K, the A-2 phase of chromium is obtained. The study of the transformation kinetics of the A-15 to the A-2 phase yields an estimate of activation energy 1.81 K cal mol-1.
