Abstract
Способ получения добавок и лигатур для производства сплавов, заключающийся в расплавлении основного металла и растворяемых ингредиентов и кристаллизации при объемном охлаждении расплава, при этом для получения легирующих добавок типа твердый раствор замещения-внедрения расплав кристаллизуют в силовом поле центрифугальной машины, отличающийся тем, что ! кристаллизацию слабоперегретого расплава заданного химического состава производят в силовом поле с соответствующим данному расплаву коэффициентом гравитации, выбранном из диапазона от 20 до 500, в футерованной (подогреваемой) изложнице ротора центрифугальной машины, в три этапа: ! на первом из которых раствор обрабатывают при равномерном объемном охлаждении залитого расплава со скоростью 0,5-10°/c в изложнице с его перегревом над ликвидус на величину обеспечения времени существования жидкой фазы расплава, достаточного для полного растворения инградиентов в расплаве в течении интервала времени ! t=m3/aKg, где а - коэффициент, Кg - коэффициент гравитации, m3 - относительная масса растворяемых ингредиентов в добавке, ! на втором этапе остывающий раствор обрабатывают в силовом поле центрифуги при выбранном коэффициенте гравитации для прохождения кристаллизации в силовом поле центрифуги до достижения остывающего расплава в изложнице кристаллизатора температуры начала процессов кристаллизации в обычных условиях, ! на третьем этапе остывающий отливок обрабатывают в силовом поле центрифуги при выбранном коэффициенте гравитации до достижения остывающего в изложнице кристаллизатора отливка температуры завершения процесса кристаллизации в обычных условиях.The method of producing additives and alloys for the production of alloys, which consists in the melting of the base metal and soluble ingredients and crystallization with volumetric cooling of the melt, while to obtain alloys of the type of solid solution of substitution-introduction, the melt is crystallized in the force field of a centrifugal machine, characterized in that! crystallization of a slightly overheated melt of a given chemical composition is carried out in a force field with a gravity coefficient corresponding to that melt, selected from a range from 20 to 500, in a lined (heated) mold of a rotor of a centrifugal machine, in three stages:! on the first of which the solution is treated with uniform volumetric cooling of the molten melt at a speed of 0.5-10 ° / s in the mold with its overheating over liquidus by the amount of the lifetime of the liquid phase of the melt sufficient to completely dissolve the ingredients in the melt during the time interval! t = m3 / aKg, where a is the coefficient, Kg is the gravity coefficient, m3 is the relative mass of soluble ingredients in the additive,! at the second stage, the cooling solution is treated in the centrifuge force field at the selected gravity coefficient to pass crystallization in the centrifuge force field until the cooling melt in the mold of the crystallizer reaches the temperature at which crystallization processes begin under ordinary conditions,! at the third stage, the cooling castings are processed in a centrifuge force field at a selected gravity coefficient until the temperature of the crystallization process ends under normal conditions when the mold cooling in the mold is reached.
