Abstract

The current transients observed during crack propagation in titanium-8 aluminum-1 molydenum-1 vanadium immersed in molten LiCI-KCI have been analyzed. The electrochemical events which cause the transients have been determined. The dominant event during the initial stages of cracking was anodic dissolution from the film-free crack walls. A film was then deposited on the walls which passivated the surface, causing a decrease in current density. The final stage involved thickening of the film. The analysis has revealed that anodic dissolution could not support the very fast crack extension described here (i.e., crack velocities greater than 10-3 cm/sec).
