Claims (5)

1. Способ термической обработки катаных полуфабрикатов или изготавливаемых из них изделий из сплавов на основе алюминия путем отжига, отличающийся тем, что отжиг проводят в две ступени, на первой из которых катаные полуфабрикаты или изготавливаемые из них изделия нагревают со скоростью более 100°С/ч до температуры в интервале с нижним пределом не ниже температуры начала рекристаллизации и верхним пределом не выше температуры солидуса алюминиевого сплава с выдержкой при этой температуре в течение не более 60 мин, а на второй ступени катаные полуфабрикаты или изготавливаемые из них изделия подвергают отжигу при температуре в интервале с верхним пределом не выше температуры минимальной устойчивости твердого раствора алюминиевого сплава и нижним пределом не ниже температуры сольвуса зон Гинье-Престона с выдержкой при этой температуре в течение не более 10 ч.1. The method of heat treatment of rolled semi-finished products or products made of them from aluminum-based alloys by annealing, characterized in that the annealing is carried out in two stages, in the first of which rolled semi-finished products or products made from them are heated at a speed of more than 100 ° C / h to a temperature in the range with a lower limit not lower than the temperature of the onset of recrystallization and an upper limit not higher than the solidus temperature of the aluminum alloy with holding at this temperature for no more than 60 minutes, and rolled on the second stage semi-finished products or products made from them are annealed at a temperature in the range with an upper limit not higher than the temperature of the minimum stability of the aluminum alloy solid solution and a lower limit not lower than the Guinier-Preston solvus temperature with holding at this temperature for no more than 10 hours. 2. Способ по п.1, отличающийся тем, что отжиг на первой ступени проводят при температуре в интервале с нижним пределом, который на 2°С, предпочтительно на 5°С, выше температуры начала рекристаллизации сплава, и верхним пределом, который на 2°С, предпочтительно на 5°С, ниже температуры равновесного солидуса, а отжиг на второй ступени проводят при температуре в интервале с верхним пределом не выше температуры минимальной устойчивости твердого раствора алюминиевого сплава и нижним пределом, который на 2°С, предпочтительно на 5°С, выше температуры сольвуса зон Гинье-Престона.2. The method according to claim 1, characterized in that the annealing in the first stage is carried out at a temperature in the range with a lower limit, which is 2 ° C, preferably 5 ° C, higher than the temperature at which the alloy recrystallizes, and the upper limit is 2 ° C, preferably 5 ° C, below the equilibrium solidus temperature, and annealing in the second stage is carried out at a temperature in the range with an upper limit not higher than the temperature of the minimum stability of the aluminum alloy solid solution and a lower limit, which is 2 ° C, preferably 5 ° C, above temperature solvus zones of Guinier-Preston. 3. Способ по п.1, отличающийся тем, что катаные полуфабрикаты или изготавливаемые из них изделия после выдержки на первой ступени охлаждают до температуры окружающей среды.3. The method according to claim 1, characterized in that the rolled semi-finished products or products made from them, after exposure to the first stage, are cooled to ambient temperature. 4. Способ по п.1, отличающийся тем, что катаные полуфабрикаты или изготавливаемые из них изделия после выдержки на первой ступени охлаждают до температуры отжига на второй ступени.4. The method according to claim 1, characterized in that the rolled semi-finished products or products made from them after exposure to the first stage are cooled to the annealing temperature in the second stage. 5. Способ по одному из пп.1-4, отличающийся тем, что катаные полуфабрикаты или изготавливаемые из них изделия после выдержки на второй ступени охлаждают до температуры в пределах от 20 до 200°С со скоростью не более 100°С/ч.5. The method according to one of claims 1 to 4, characterized in that the rolled semi-finished products or products made from them, after exposure to the second stage, are cooled to a temperature in the range from 20 to 200 ° C at a speed of not more than 100 ° C / h.
