(54) СПОСОБ ОБРАБОТКИ МЕТАЛЛОВ И СПЛАВОВ(54) METHOD FOR TREATING METALS AND ALLOYS
Изобретение относитс к металлург гни, в частности к способу обработки металлов и сплавов, и может быть использовано в радиоэлектронике н приборостроении. Известен способ обработки металлов и сплавов путем термоциклировани их при давлении 10 - 10 ат в. интервале температур от 0,4-0,7 Т пл до 0,8-0,9 Т пл. К 1. Однако этот способ требует дл своей реализации дорогосто щего оборудовани , так как высокотемпературные отжиги ведут с при повышенных давлени х. Известен также способ обработки металлов и сплавов путем нагрева их в вакууме при давлении остаточных газов мм рт.ст. и температуре 0,4-0,7 Т пл. К 2. Однако этот способ не обеспечивает повышение пло ности металлов и сплавов,в которых отсутствуют фазовые превращени , Целью изобретени вл етс повышение плотности металлов и сплавов. Поставленна цель достигаетс еле . дующим образом. Металлы и сплавы предварительно подвергают пластической деформации на 2-5%, а затем наг ревают в вакууме при давлении Ьстаточных газов 10 - 10 мм рт.ст. при температуре 0,4-0,7 Т пл.К и выдерживают при этой температуре в течение 5-10 час. Существенное отличие способа состоит в предварительной пластической деформации на 2-5%, а также регламен тированной выдержке при нагреве. Положительный эффект способа обусловлен инициированием процессов испускани парами и трещинами точечных дефектов, в частности вакансий. По предложенному способу обрабатывали поликристаллические образцы меди марки Ml и(Монокристаллического молибдена. Образцы подвергали деформации на 2,3 и 5%, после чего нагревали до температуры (медные образцы) и (образцы; «)нокрис- таллов молибдена) выдерживали в течение 5 и 10 час. Плотность образцов оценивалась по относительному изменению объема (AV/V), который определ лс дифференциальным методом гидростатического увешивани . В ,таблице привод тс сравнитель 1ые данные по плотности образцов обработанных по известному и предложенному .способам.The invention relates to metallurgy rot, in particular to a method for processing metals and alloys, and can be used in radio electronics and instrument engineering. A known method of processing metals and alloys by thermal cycling them at a pressure of 10 - 10 at. temperature range from 0.4-0.7 T pl to 0.8-0.9 T pl. To 1. However, this method requires expensive equipment for its implementation, since high-temperature annealing is carried out at elevated pressures. There is also known a method of processing metals and alloys by heating them in vacuum at a pressure of residual gases mm Hg. and a temperature of 0.4-0.7 T pl. C 2. However, this method does not provide an increase in the density of metals and alloys in which phase transformations are absent. The aim of the invention is to increase the density of metals and alloys. The goal is achieved barely. blowing way. Metals and alloys are preliminarily subjected to plastic deformation by 2–5%, and then heated in vacuum at a pressure of 10 to 10 mm Hg. at a temperature of 0.4-0.7 T pl.K and maintained at this temperature for 5-10 hours. The essential difference of the method consists in the preliminary plastic deformation by 2–5%, as well as by the regulated exposure to heating. The positive effect of the method is due to the initiation of emission processes in pairs and cracks of point defects, in particular vacancies. According to the proposed method, polycrystalline copper samples of grade Ml and (monocrystalline molybdenum were processed. The samples were subjected to deformation by 2.3 and 5%, then heated to temperature (copper samples) and (samples; ") molybdenum crystals) were kept for 5 and 10 hours The density of the samples was estimated by the relative volume change (AV / V), which was determined by the differential hydrostatic suspension method. Table 1 gives a comparison of the 1st data on the density of samples processed according to the known and proposed methods.
Как видно из таблицы, после обработки как медных образцов, так и монокристаллического молибдена исходит значительное уменьшение удельного объема, а следовательно, увеличение плотности образцов.As can be seen from the table, after processing both copper samples and single-crystal molybdenum, a significant decrease in the specific volume proceeds, and, consequently, an increase in the density of the samples.
