The influence of rare earth metals, such as praseodymium, neodymium, and erbium, and the technology of smelting a nickel aluminide alloy based on “clean” raw materials and using 25, 50, and 75 wt % of waste is investigated. It is found that doping with neodymium and/or erbium in the smelting of structural intermetallic nickel-based alloy increases the heat strength at a temperature of 1200°C and heat resistance at the temperatures of 1100 and 1200°C for 100 h at a weight gain from 1 m2. Introducing a different percentage of waste during the smelting the intermetallic alloy results in a slight decrease in the heat resistance but preserves the same level of values when 25, 50, or 75 wt % of waste is included.
