martensite

Regulation of the phase-structural composition and metastability of austenite by alloying elements and parameters of tempering for increase wear-resistance of Fe-Cr-Mn deposited steel

It is shown that under the influence of alloying (Cr, Mn, C, Si, Ti, N, V) during electric arc hardfacing with a flux cored wire, as well as technological tempering parameters at temperatures of 300...700°C, the phase-structural composition of the cost-saving alloyed deposited steel (from 0 to 75 % quenching martensite and austenite), the degree of metastability of austenite are regulated.
