Hydrogen in metals

The effects of hydrogen on various metals and the use of metal hydrides for hydrogen storage are discussed. The mechanisms of, and differences between , hydrogen embrittlement and hydrogen attack of ferritic steels are compare d, common sources of hydrogen in metals processing and treatment identified , and mechanisms for hydrogen entry into a ferritic surface are discussed. The differences between hydrogen attack of ferritic steels and copper alloy s are contrasted, and an unusual case study of hydrogen embrittlement of an alloy steel is presented.
