| Summary: | Title screen The effect of initial heat treatment on peculiarities of ultrafine-grained structure and on homogeneity of strength properties (microhardness) through the specimens was studied in low-carbon steel Fe-Mo-Nb-V-C processed by high-pressure torsion. Three initial states, i.e. (I) normalized, (II) quenched and (III) quenched and tempered, with different morphologies and grain sizes were used. A noticeable effect of the initial state on characteristics of ultrafine-grained structure processed by high-pressure torsion was observed: decrease in the initial grain size causes more effective grain refinement and formation of higher value of microhardness in the middle part of disk radii (d[av]=1 nm and 700 HV for normilized state, d[av]=98 nm and 770 HV for quenched state and d[av]=100 nm and 600 HV for initial quenched and tempered state).
