Conclusions

  1. 1.

    The strength of steel 1Kh12V2MF at room and operating temperatures decreases in proportion to the logarithm of the mean distance between hardening particles. This relationship holds true for the metal aged under stress and without stress and also for the metal tested after prolonged operation.

  2. 2.

    The time to failure of the aged metal decreases with increasing distance between particles. The rate of the decrease depends on the type of hardening phase. The time to failure after creep is shorter than after aging due to the microdefects in the structure resulting from creep.
