FIELD: powder metallurgy. SUBSTANCE: method involves melting burden while introducing wastes in the form of billets produced by baking granular wastes in ceramic crucible under vacuum at residual pressure of 13.3-1.33 Pa and temperature of 0.8-0.98 of alloy melting temperature. EFFECT: reduced loss of expensive metal and, as a result, reduced cost of articles obtained. 2 tbl
