Evidence for the transport of impurity hydrogen with gliding dislocations in aluminum

A tritiated pure aluminum specimen was autoradiographically processed with a plastic strain of 5% prior to exposure. Microscopic autoradiographs revealed a clear evidence for hydrogen transport with gliding dislocations: an array of silver particles, i.e. tritium, was evident on the slip steps on th...

Zusammenfassung:	A tritiated pure aluminum specimen was autoradiographically processed with a plastic strain of 5% prior to exposure. Microscopic autoradiographs revealed a clear evidence for hydrogen transport with gliding dislocations: an array of silver particles, i.e. tritium, was evident on the slip steps on the specimen surface.
