Research on the Kinetics of Phase Changes in Solids.

Abstract

A brief outline is presented of experimental observations and theoretical interpretations of hydrogen embrittlement of steels. Detailed results on the effect of precharged hydrogen on reduction in ductility of low-strength steels under plane strain loading are discussed. Under such conditions hydrogen is shown to degrade the steels by promoting plastic instability in the form of shear bands, lowering the critical strain for various events without changing the locally ductile mode of fracture.
