Conclusions

  1. 1.

    The cyclic instability associated with the alloys tested is a function of their structural instability at the test temperature.

  2. 2.

    The increase in the cycle threshold amplitude for structurally unstable alloys at high temperatures is due to the increased friction stress that prevents movement by the dislocations. The increased friction stress is related to the pinning of the dislocations by precipitates.
