Abstract
Measures for utilization of technogenic metallurgy wastes in the production of high quality alloys are proposed. Temperature dependences of physical properties of liquid superalloys are investigated, critical temperatures are determined, heating above which leads to irreversible intensive changes in the state of the melt. The relationship between the amount of cast waste in the scrap and features of temperature dependences of physical and chemical properties of the melt has been established. The increase in the amount of waste leads to the growth of critical temperatures. Application of high-temperature treatment allows to improve considerably the quality of casting superalloys, the scrap of which contains a large amount of foundry technogenic wastes.
