Claims (1)

Способ термической обработки конструкций, выполненных из мартенситно-стареющей стали, включающий закалку, обработку холодом при температуре 50 - 70oC и отпуск при 200 - 250oC, отличающийся тем, что при обработке паяно-сварных конструкций, содержащих детали из мартенситно-стареющей стали и дисперсионно-твердеющего сплава на никелевой основе, закалку совмещают с пайкой конструкции и осуществляют при температуре 1200 ± 10oC с выдержкой при ней 6 - 9 мин и охлаждением со скоростью 50 - 70oC/мин, а перед обработкой холодом конструкцию подвергают двухкратному нагреву при температуре 860 ± 10oC, выдержке при ней 5 - 10 час и охлаждению на воздухе.The method of heat treatment of structures made of maraging steel, including hardening, cold working at a temperature of 50 - 70 o C and tempering at 200 - 250 o C, characterized in that when processing brazed-welded structures containing parts from maraging steel steel and a precipitation hardening alloy based on nickel, the quenching is combined with the soldering of the structure and carried out at a temperature of 1200 ± 10 o C with holding it for 6 - 9 min and cooling at a speed of 50 - 70 o C / min, and before cold treatment the structure is subjected two times mu heating at a temperature of 860 ± 10 o C, holding at its 5 - 10 hours and air cooling.
