Description

заготовок каждого сплава были обработаны по двум вариантам с пониженными и повышенными параметрами обработки относительно предлагаемых пределов. Кроме того, три заготовки каждого сплава были обработаны по известному способу. Режимы получени  кованых полуфабрикатов приведены в таблице. Деформирование во всех случа х проводили со скоростью деформации - -10 4с 1. Из полученных поковок были вырезаны образцы дл  исследовани : из наиболее деформированной центральной зоны и из наименее деформированных зон затрудненной деформации (прилегающих к контактной поверхности при последней осадке при 1000°С).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).
