Creep damage is the result of slow plastic flow of metal under stress and at high temperature, typically about 50% of the absolute melting temperature. If there is enough creep damage, the end result can be sudden, catastrophic failure. Lately, creep has become a serious problem in the petrochemical industry and in fossil fuel power plants, where alloy steel pipes are subjected to stress and high temperature for long periods of time.
