Article

Results are presented for a study of the macro- and microstructure of ingots, granules, and experimental compacted specimens of a new nickel-base superalloy. Features are emphasized most strongly affecting mechanical properties of finished objects prepared from nickel-base superalloy granules, and in fact the size of a dendrite cell, morphology, carbide and γ′-phase size, and solid solution grain size.

Keywords
