摘要：

Results of investigation of the life of D16 T, AK4‐1 T1, and 1201 T1 aluminum alloys are generalized on the basis of the kinetic concept of failure. The life is studied under creep at constant loads and loads increasing with different rates and at different temperatures. The temperature is varied within the range of 473–77 K, and the duration of tests ranges from fractions of a second to ten thousand hours. Information on the effect of internal‐stress relaxation on the life of alloys is obtained. A method for predicting the life with allowance for relaxation processes in solids is verified experimentally.
