Abstract
Способ получения отливок с направленной структурой из жаропрочных сплавов, включающий изготовление оболочковой формы, нагрев ее до температуры выше температуры ликвидуса жаропрочного сплава, заполнение формы расплавом и направленную кристаллизацию с помощью затравки из тугоплавкого материала, затравку размещают в донной части формы перед ее подогревом, отличающийся тем, что затравку изготавливают литьем в вакуумной печи в форме с открытым дном, установленной на медный неохлаждаемый кристаллизатор, форму с затравкой извлекают из печи после ее охлаждения, затем осуществляют механическую обработку - шлифование, контактной поверхности затравки с холодильником на глубину зоны аморфных замороженных кристаллов и глубокое травление до образования в структуре рельефа поверхностного слоя затравки выраженных межзеренных границ.A method of producing castings with a directional structure from heat-resistant alloys, including the manufacture of a shell mold, heating it to a temperature above the liquidus temperature of the heat-resistant alloy, filling the mold with melt and directional crystallization using a seed from a refractory material, the seed is placed in the bottom of the mold before heating, characterized in that the seed is made by casting in a vacuum furnace in the form with an open bottom mounted on a copper uncooled mold, the form with the seed is removed from the furnace after cooling, is then carried machining - grinding, the contact surface of the seed with a refrigerator to a depth of frozen crystals amorphous zones and deep etching to form the relief structure in the surface layer of the seed grain boundaries marked.
