Conclusions

  1. 1.

    Plastic deformation substantially accelerates precipitation of σ phase and carbides TiC and (Ti, Ni)6C in steel 12Kh18N10T, the intensifying effect decreasing notably when the rolling temperature is raised from 20 to 1000°.

  2. 2.

    Plastic deformation substantially reduces the fracture toughness of steel 12Kh18N10T after prolonged holding at 650°. The fracture toughness decreases least after high-temperature and cold deformation with 15% reduction.

  3. 3.

    The effect of preliminary polygonization annealing on the properties of steel 12Kh18N10T is retained during subsequent heating to 650° for as long as 500 h.

  4. 4.

    The structure resulting from high-temperature deformation is the most stable during prolonged heating at 650°.
