Abstract

Изобретение относится к области металлургии, а конкретно к процессам получения новых металлических материалов различной природы, в частности получения слоистых металлических материалов. Способ получения слоистых металлических материалов путем кристаллизации в силовом поле центрифуги, характеризующийся тем, что слабоперегретые расплавы металлов или сплавы, отличающиеся друг от друга химическим составом, из отдельных плавильных зон заливают один поверх другого в заданной последовательности и в заданных объемах во вращающийся футерованный кристаллизатор центрифуги, выполненный с термодинамическими характеристиками кристаллизатора, обеспечивающими объемное равномерное охлаждение расплава со скоростью не выше 0,5%, обороты ротора центрифуги устанавливают для создания коэффициента гравитации в диапазоне от 20 до 300 и сохраняют перегрев залитых расплавов в течение времени нахождения их в жидкой фазе для прохождения процессов диффузии и проведение направленной кристаллизации до начала процессов естественной кристаллизации, при этом вращение центрифуги сохраняют до достижения охлаждающейся отливки температуры завершения естественных процессов кристаллизации используемых расплавов, а после достижения остывающей отливки температуры завершения естественных процессов кристаллизации, центрифугирование прекращают для дальнейшего охлаждения отливки. Достигаемый технический результат заключается в получении многослойных отливок с более высокими параметрами прочности и структурной однородности, что приводит к резкому (до 25-30%) повышению служебных свойств.The invention relates to the field of metallurgy, and specifically to processes for producing new metal materials of various nature, in particular the production of layered metal materials. A method for producing layered metal materials by crystallization in a centrifuge force field, characterized in that slightly overheated metal melts or alloys differing in chemical composition from individual melting zones are poured one on top of the other in a given sequence and in given volumes into a rotating lined centrifuge mold, made with the thermodynamic characteristics of the mold, providing volumetric uniform cooling of the melt at a rate of no higher than 0.5%, about The rotor rotor’s orbits are set to create a gravity coefficient in the range from 20 to 300 and the overheated melts are kept overheated during the time they are in the liquid phase to undergo diffusion processes and directional crystallization is carried out before natural crystallization begins, while the centrifuge rotates until the cooling casting is reached the temperature of completion of the natural crystallization processes of the melts used, and after reaching the cooling casting, the temperature of completion is governmental crystallization processes, centrifugation is stopped for further cooling of the casting. The technical result achieved is to obtain multilayer castings with higher strength parameters and structural uniformity, which leads to a sharp (up to 25-30%) increase in service properties.
