Conclusions

  1. 1.

    Phase composition, position and degree of dispersion for secondary phases in steel 15Kh2NMFA do not change with a changeover from bending at 20°C to bending at 620°C.

  2. 2.

    Polygonization of metal bent at 620°C occurs more completely and the level of microstresses is an order of magnitude less than in the process of bending at normal temperature.

  3. 3.

    The more stable dislocation structure formed during bending at 620°C provides less loss of strtength for steel 15Kh2NMFA during additional tempering.
