Established that at the increase of the mass fraction of carbon from 0.09% to 0.30% in the as-cast metal, the metal hardness increases. At the same time, the structural-phase composition consists of a pseudo-pearlitic structure (ferrite-nitride mixture) and austenitic structure in different ratios since an increase in the carbon content leads to an increase in the amount of the pseudo-pearlite. The heat treatment of specimens with the mass fraction of carbon of 0.09% and 0.30% at 1250 °C for two hours leads to their complete austenization. In this case, the hardness of steels of both compositions decreases to 22 – 24 HRC (0.09 wt.% of carbon) and to 28 – 30 HRC (0.30 wt.% of carbon).

The alloy strengthening and/or softening during further natural aging up to 500 hrs were within 10-15% and controlled by simultaneous decomposition of the aluminum solid solution and recovery of its deformation structure.

An additional high-temperature annealing step resulted in some reduction in the alloy strength, but was effective in eliminating the chemical heterogeneity of the cast structure and increasing corrosion resistance while maintaining the grain size and dispersity and coherency of the nanosized Al3(Sc,Zr) dispersoids present in the alloy.
