the bonding force reduction [37], local plastic deformation [38], surface energy reduction [39], and hydrogen pressure theories [40]. A commonality among all of the proposed mechanisms is the permeation of hydrogen atoms into high-stress regions in metal and the subsequent reduction in deformation capacity when the hydrogen concentration reaches a critical threshold. Reactions of the cathode include......
