Thermomechanical Treatment of Metals


  1. 1.

    HTTMT refines the grains and changes their shapes; the grain boundaries are more curved and longer.

  2. 2.

    The strengthening effect of HTTMT is stable up to high tempering temperatures (550°C for 30KhGSA steel) and is retained after multiple polymorphous transformations.
