Description
Способ осушес-юл ют следующим образом Листы толшиной 10 мм из сплава 01420 системы алкллнний - магний - литий нагревают по режимам, соотьетствуюшим npecyiaгаемому и вэвестному способам,The method of drying is as follows. Sheets with a thickness of 10 mm from alloy 01420 of the system alklnnii - magnesium - lithium are heated according to the regimes corresponding to the npecyia and well-known methods,
1.Нагрев дб в вакууме 1 10 мм рт.ст., снижение глубины вакуума до О,4г10 мм рт.ст., нагрев до 470 С выдер 1жа 12 ч, (предлагаемьШ способ),1. Heating dB in vacuum 1 10 mm Hg, reducing the depth of the vacuum to 10, 4g10 mm Hg, heating to 470 вы for 12 h, (the proposed method),
2.Отжиг при 47О°С в течение 12 ч. при глубине вакуума 1 Ю мм рт.ст, (известный способ)2. Burning at 47 ° C for 12 hours with a vacuum depth of 1 U mm Hg (known method)
После вакуумного отжига по режимам 1 и 2 листы подвергают электроннолучевой сварке и упрочн кицей термической обработ ке: закалка с на воздух и старение при 120 С в течение 12 ч.After vacuum annealing according to modes 1 and 2, the sheets are subjected to electron beam welding and hardened with a heat treatment: hardening with air and aging at 120 C for 12 h.
Результаты исследовани полуфабрикатов приведены в та|блиае.The results of the study of semi-finished products are given in the table.
Таким образом, превдагаемый способ по сравнению с известным обеспечивает более высокий уровень механических свойств основного металла и с|Варных соединений, исключает или существенно уменьшает ве личвду обевненного легирующими элёмеатами поверхностного сло .Thus, the advanced method, in comparison with the known method, provides a higher level of mechanical properties of the base metal and with | Varny joints, eliminates or significantly reduces the value of the surface layer depleted by alloying elements.
