The structure of model specimens and articles fabricated from medium-carbon high-strength steels is studied for developing modes of forming of working members of tilling machines with cutting edges thinned without the expensive operation of electromachining. The effect of the temperature of heating of billets on the grain size of austenite is determined. The kinetics of recrystallization is studied in the temperature, rate and strain ranges typical for hot forming. A quantitative crystallographic analysis of the microstructure is performed by the EBSD technique. The degrees of distortion of the crystal lattices of structural components and the mean sizes of martensite blocks are determined.
