Abstract

A technology is developed for preparing wrought superalloy VZh175 for turbine disks using up to 100% conditioned waste. The technology developed makes it possible to obtain alloy no worse than that prepared from fresh charge materials with respect to alloying element content, impurities, structure, and mechanical properties. The cost of the alloy made using 100% conditioned waste is 20–30% lower than that for alloy melted by industrial technology using up to 50% conditioned waste.
