Abstract
Изобретение относитс к термической обработке алюминиевых сплавов, в частности сплавов на основе AL-CU-MN. Цель изобретени - повышение прочности, пластичности и снижение склонности короблению. Способ термической обработки включает закалку и старение, а перед закалкой сплав подвергают термоциклированию путем нагрева до температуры закалки, охлаждению на воздухе до температуры солидуса с числом циклов 10-15, причем последнее охлаждение провод т в воде комнатной температуры. 1 табл.This invention relates to the heat treatment of aluminum alloys, in particular alloys based on AL-CU-MN. The purpose of the invention is to increase the strength, ductility and reduce the tendency to warp. The method of heat treatment includes quenching and aging, and before quenching the alloy is subjected to thermal cycling by heating to the quenching temperature, cooling in air to the solidus temperature with a number of cycles of 10-15, the latter cooling is carried out in room temperature water. 1 tab.
Description
Изобретение относитс к области термической обработки алюминиевых сплавов, в частности Л1 тейньгх сплавов на основе Al-Cu-Mn, подвергаемых термической упрочн ющей обработке.The invention relates to the field of heat treatment of aluminum alloys, in particular L1 teing alloys based on Al-Cu-Mn, subjected to heat strengthening treatment.
Цель изобретени - повышение прочности , пластичности и снижение склонности и короблению.The purpose of the invention is to increase strength, ductility and reduce inclination and warping.
Пример. Способ обработки использовали на отливках сплава ВАЛЮ, Химический состав сплава, %: Си 4,5; Мп 0,7; Ti 0,2; Cd 0,15. Вследствие большой разницы в атомных радиусах алюмини и кадми сплав отличаетс повьшенной искаженностью кристаллической решетки и склонностью к деформации .Example. The method of processing was used on castings of the alloy WALLU, Chemical composition of the alloy,%: Cu 4,5; Mp 0.7; Ti 0.2; Cd 0.15. Due to the large difference in the atomic radii of aluminum and cadmium, the alloy is characterized by a higher distortion of the crystal lattice and a tendency to deform.
Образцы перед закалкой проходили термоциклическую обработку в интервале температур 545 5, 10, 13,Before quenching, the samples underwent thermocyclic treatment in the temperature range 545 5, 10, 13,
15 и 20 циклов. От последнего цикла нагрева производилась закалка с охлаждением в воде комнатной температуры . Старение сплава проводили по режиму 170 С 7 ч. Дл определени склонности к деформации исползовали кольца переменного сечени . Деформаци колец определ лась по изменению рассто ни между метками, нанесенными на кольце после его разрезки.15 and 20 cycles. From the last heating cycle, quenching was performed with cooling in water at room temperature. The aging of the alloy was carried out according to the 170 ° C regime for 7 hours. Variable cross section rings were used to determine the tendency to deform. The deformation of the rings was determined by the change in the distance between the marks on the ring after it was cut.
Механические испытани проводили на образцах, выполненных по ГОСТ ;1497-84. Нагрев образцов проводилс со скоростью 5 С/мин, охлаждение доMechanical tests were carried out on samples made according to GOST; 1497-84. The samples were heated at a rate of 5 C / min, cooled to

Таким образом, предварительна термоцнклическа обработка сплава, предшествующа закалке, обеспечивает повышение прочностных и пластических свойств сплава в сочетании с низкой их склонностью к деформации.Thus, the preliminary thermal treatment of the alloy prior to quenching improves the strength and plastic properties of the alloy in combination with their low tendency to deform.
