The paper presents the results of further development of the technology of growing superlarge single-crystals of refractory metals, developed at PWI of the NAS of Ukraine. Proceeding from the optimized technology and acquired experience, new generation equipment was manufactured, which allows growing single-crystals of refractory alloys in the form of a body of revolution. Experiments were performed on growing tungsten single-crystals in the form of a hollow cylinder, which can be used to manufacture such a product as a crucible. Technological parameters and energy modes were established, which allowed controlling the thickness of the wall being deposited. As a result of the experiments, an ingot with the deposited wall height of 68 mm, thickness of 20-22 mm and outer diameter of 85 mm was grown. [ABSTRACT FROM AUTHOR] |
