Abstract : In practice, the methods often proposed to prevent the hydrogen embrittlement problems involve design modification, changes in fabrication techniques, changes in material properties such as composition and heat treatment which involve changes in yield strength and microstructure of the material, and environmental control such as anodic or cathodic protection or lowering of the concentration of certain embrittling species such as H, H2S, Cl, etc.
