Conclusions

  1. 1.

    Phase strain hardening with subsequent aging at 600°C is the most effective means of strengthening austenitic Fe−Ni−Ti steels by heat treatment. The following mechanical properties can be obtained: δB=105-120 kg/mm2, δ0.2=90-95 kg/mm2, δ=20–22%, ψ=40–45%.

     
  2. 2.

    Austenitic Fe−Ni−Ti steels are strengthened most by aging at temperatures where the solid solution decomposes (550–600°C) with subsequent deformation at the same temperatures: δB=150-170 kg/mm2, δ0.2=115-125 kg/mm2, δ=30–35%, ψ=40–50%.

     
  3. 3.

    Metastable austenitic Fe−Ni−Ti steels have a high plasticity after strengthening, since stresses exceeding the yield strength induce the martensitic transformation, causing stress relaxation and increasing the capacity of the steel for plastic deformation.
