90 . 1 Изобретение относитс к металлургии , в частности к термической обработке двухфазных магниево-литиевых сплавов, и может быть использовано в авиационной промышленности И в машиностроении. Цель изобретени - повышение механических свойств, снижение скорости установившейс ползучести и сокращение длительности термической обработки. По предлагаемому способу обраба- тывают деформированные заготовки из сплава МА21 сечением 20x20 мм. Заготовки нагрев от в ванне состава, %: LiCl 60 и КС1;4адо 530-5бЬ«Св тече12 ние 9-10 мин со скоростью 1,3 1 ,5 С/с,, а затем следует охлаждение заготовок с ра зличной скоростью. Р д заготовок охлаждают в воде с температурой 25 С, другие заготовки - в воде с температурой 40 и , а часть заготовок охлаждают на возДУхе . Параллельно обрабатывают такие же брйзцы сплава МА21 по известному способу. На обработанных заготовках определ ют механические свойства и провод т испытани на ползучесть. ;Результаты испытаний приведены в таблице.90. 1 The invention relates to metallurgy, in particular to the heat treatment of two-phase magnesium-lithium alloys, and can be used in the aviation industry and in mechanical engineering. The purpose of the invention is to increase the mechanical properties, reduce the steady-state creep rate and reduce the duration of heat treatment. According to the proposed method, deformed blanks of MA21 alloy with a section of 20x20 mm are processed. The blanks are heated from the composition of the bath,%: LiCl 60 and KC1; 4ADO 530-5Bb “For 9-10 minutes at a speed of 1.3-1.5 C / s, and then the cooling of the blanks follows at a different rate. A number of blanks are cooled in water with a temperature of 25 ° C, other blanks are cooled in water with a temperature of 40 ° C, and some of the blanks are cooled by air. In parallel, they process the same MAss alloy MA21 by a known method. Mechanical properties are determined on the treated blanks and creep tests are carried out. The test results are shown in the table.
