Conclusion

  1. 1.

    Aging of high-manganese 110G13L steel at temperatures from 200 to 400°C permits to increase its ultimate strength without changing the yield stress, while plastic properties, and the semibrittleness temperature T50 slightly decrease. Aging at temperatures above 400°C leads to sharp reduction of σB, ψ, δ and T50.

     
  2. 2.

    After fractional loading of the 110G13L steel at temperatures of 20–250°C an increase of σ0.2 and σB is achieved; the plastic properties decrease in cold strain while in thermal strain they do not change.

     
  3. 3.

    The process of plastic strain of the 110G13L steel with subsequent aging causes an increase of strength properties without reducing plasticity. Apparently this takes place on account of the separation during aging of dispersed particles along the slip planes, produced by preliminary deformation.
