Abstract
Strengthening of palladium using hydrogen-induced transformation hardening (“hydrogen phase naklep” (HPN)) in the course of the reverse β → α hydride phase transformation in palladium-hydrogen alloys has been studied. It has been shown that the degree of HPN is mainly determined by the difference of the specific volumes of the transforming phases. As the transformation temperature decreases and the difference of the specific volumes of the transforming phases increases, the degree of strengthening of palladium during HPN systematically increases and its plasticity decreases, which is accompanied by an increase in the dislocation density and magnitude of microdistortions and by a decrease in the dimensions of the mosaic blocks.
