Description

the blanks of each alloy were machined in two versions with reduced and increased processing parameters relative to the proposed limits. In addition, three blanks of each alloy were processed by a known method. Modes of preparation of forged semi-finished products are shown in the table. In all cases, deformation was carried out with a strain rate of -10 4s 1. Samples for investigation were cut from the obtained forgings: from the most deformed central zone and from the least deformed zones of difficult deformation (adjacent to the contact surface during the last settlement at 1000 ° C).
The structure of the cut samples with an estimate of the degree of recrystallization was studied.
lization A, the size of the recrystallized grains Dp and the mechanical properties of the ultimate strength (7p, elongation d, at a temperature of 20 and 600 PS. The results of the studies are shown in the table.
Based on the data given in the table, the following conclusions can be drawn: due to a more homogeneous and fine-grained structure, the values of plastic characteristics (3) at temperatures of 20 and 600 ° C) increase by 25-30% with an unchanged strength level.
