Abstract
The scientific and applied aspects of growing single crystals of refractory metals using plasma and induction heating sources are considered. The technological advantages of combined plasma-induction heating when growing large single crystals of refractory metals, in particular tungsten and molybdenum, are shown. The design of the UP-122M pilot plant for growing flat single crystals of tungsten and molybdenum and its technical characteristics are given. The problems of formation of the structure of tungsten single crystals under the conditions of hybrid plasma-induction heating are considered, and its advantages are compared with other heating methods. Ref. 11, Fig. 7.
Keywords: single crystal; plasma; induction heating; local metal bath; dislocation; layer melting; crystal formation; arc plasmatron
