摘要
A method of non-destructive evaluation of stress corrosion cracking of structural components made of metal alloys, and a method of evaluation of the remaining lifetime of the structural component made of metal alloys are provided, in which a change in properties of the structural components made of metal alloys being used in operating nuclear power plants is measured according to the degree of atomic ordering (or short range ordering) of alloying atoms, and stress corrosion cracking of the structural components made of metal alloys is thus evaluated. The properties to be measured may be one or more selected from a group consisting of hardness, electrical resistivity and thermal conductivity.
