Description

(54) СПОСОБ ОБРАБОТКИ АЛЮМИНИЯ И ЕГО СПЛАВОВ(54) METHOD FOR PROCESSING ALUMINUM AND ITS ALLOYS

II

Изобретение относитс  к металлургии и машиностроению и может быть использовано при гор чей деформационной обработке изделий из алюмини  и его сплавов ..The invention relates to metallurgy and mechanical engineering and can be used in the hot deformation processing of products from aluminum and its alloys.

Одним из важнейших параметров микроструктуры , существенно вли ющих на свойства материалов,  вл етс  средний разйл&р зерен. Уменьшение среднего размера зерна благопри тно вли ет практ чесхв на все механические свойства, т.е. существенно повышаютс  прочность и эластичность, возрастает предел текучео ти. Наличие мелкозернистой структуры  вл етс  одним из условий про влени  сверхпластичности.One of the most important parameters of the microstructure, which significantly affects the properties of materials, is the average & p grains. A decrease in the average grain size favorably affects practically all mechanical properties, i.e. strength and elasticity increase significantly, yield point increases. The presence of a fine-grained structure is one of the conditions for the manifestation of superplasticity.

Однако в большинстве алюминиевых сплавов, обработанных обычным способом, а именно механической обработкой и последующим рекристаллизационным отжигом получить мелкозернистую структуру невозможно .However, in most aluminum alloys, processed in the usual way, namely by machining and subsequent recrystallization annealing, it is impossible to obtain a fine-grained structure.

Известны способы получени  мелкозернистой структуры в алюминиевых сплавах Known methods for obtaining fine-grained structure in aluminum alloys.

Однако такие способы включают в с&б  сложную термсмеханическую обработку , занимающую много времени, и применимы лишь дл  некоторых алюминиевых сплавов, либо содержащих определенные элементы, такие, как хром или цирконий, либо дисперсионно-твердекжшх. Получе1Шв However, such methods include in S & B complex thermomechanical processing, which takes a long time, and is applicable only to some aluminum alloys, either containing certain elements, such as chromium or zirconium, or dispersion hardening.

10 же мелкого зерна в чистом алкминив и его твердых растворах известными способами невозможно.10 of the same fine grains in pure alcminiv and its solid solutions by known methods is impossible.

Известен способ получени  мелкозернистой структуры в дксперсионно-тверде«S ющих алюминиевых сплавах, заключающийс  в последующих операци х: нагрев до температуры обработки на твердый раствор дл  растворени  по крайней мере фазы , обеспечивающей впоследствии диспер20 сионное твардение; охлаждение до температуры ниже температуры растворени ; нагрев до температуры, превышающей температуру дисперсионного твердени  сплава,A known method for producing a fine-grained structure in a solid-hardening aluminum alloy, consists of the following operations: heating to the solution treatment temperature to dissolve at least the phase that subsequently ensures dispersion; cooling to a temperature below the dissolution temperature; heating to a temperature above the temperature of the precipitation hardening of the alloy,
