摘要：
By adding small amount of Mg to the wrought superalloys,the steady stage of creep,and es-pecially the tertiary stage of creep are prolonged.Also,the steady creep rate is decreasedwithin the range of low strain rates.At higher strain rates,however,the effect of Mg on creeprate vanishes.This may be attributed to the Mg dissolution in the matrix.A mechanism of theeffects of Mg addition on creep behaviors is proposed.
