Structure of NiCrAlY metal powders
vol. 35 (1997), no. 3, pp. 188 - 197

Initial structure of metallic powders can be a possible source of structural inhomogeneities found in plasma spray coatings. These powders prepared by rapid solidification techniques result in appropriate non-equilibrium phases and structures. Results of structural studies performed by light microscopy, SEM, TEM, and EDX on NiCrAlY metallic powders are presented in this paper. The structure was found consisting of a mixture of phases including β-NiAl, martensitic NiAl, γ and γ'. Y is bound in Ni5Y yttride localized in the grain boundary regions.

Key words
