Abstract

An explanation of the slow crack-growth phenomenon in gaseous hydrogen embrittlement is suggested on the basis that chemisorption is the rate-limiting step. The basis of the analysis is the existence of a mobile adsorbed species which is a prerequisite to the occurrence of slow crack growth. The disappearance of the mobile species with increasing temperature results in the observed crack-velocity dependence on temperature. The analysis is able to account qualitatively for the observed dependence of crack velocity with pressure in the different temperature regions of crack growth.
