Conclusions

  1. 1.

    A reduction in grain size (by different methods) makes it possible to lower significantly the cold-shortness temperature of high-chromium alloys of the Fe-Cr-5% Al system.

  2. 2.

    The increase in the cold-shortness temperature of Fe-Cr-5% Al alloys with increasing grain size is described by a type of Holl-Petch relationship.

  3. 3.

    The tendency of alloys of the Fe-Cr-5% Al system to embrittlement as grain size increases intensifies with their increasing chromium content.
