摘要： PROBLEM TO BE SOLVED: To provide a reliable method of predicting hydrogen embrittlement of a metal for a metallic member used for a long time by considering many environmental conditions. SOLUTION: The method of predicting hydrogen embrittlement of a metal comprises steps of: calculating the hydrogen concentration distribution in a metal after the expiration of a predetermined time based on a relational expression, concerning the hydrogen concentration in the metal and time, including a term representing the overall diffusion of hydrogen in the entire metal, a term representing the diffusion of hydrogen according to the temperature gradient of the metal, a term representing the diffusion of hydrogen according to the stress applied to the metal, and a term representing the amount of hydrogen penetrating through the metal from outside; and predicting the occurrence of hydrogen embrittlement, when or where the hydrogen concentration in the metal obtained from the hydrogen concentration distribution exceeds a predetermined value.
