Conclusions

  1. 1.

    In quenched high-carbon alloyed and unalloyed steels 9KhS and U12 and also in high-speed steels R18 and R9 the bending strength increases with the aging time, reaches a maximum, and then decreases.

  2. 2.

    Excess heating does not increase the effect of aging in high-carbon steel.

  3. 3.

    Quench-aging is a particular case of creep under the influence of internal first-order stresses. At low stresses the weakening processes develop slowly and in the first period of aging are overshadowed by the hardening resulting from structural transformations.
