The feasibility of producing alloy on cobalt base with applying the different-fraction composition of charge material was considered. The coefficients of transition of charge elements were found and microstructure of produced cobalt alloy was examined. The qualitative distribution of alloying elements in all the ingot structure was provided. Ref. 4, Tabl. 5, Fig. 5.
