Abstract

The article presents a research on development of methods to assess the geometric characteristics and volume fraction of porosity, the geometric characteristics and volume fraction of eutectic (γ-γ)ʹ-phase, and the geometric characteristics of particles of the hardening γʹ-phase in monocrystalline Ni superalloys ZhS32U-VI. The results of investigations on proposed methods of quantitative metallographic analysis of blanks from the ZhS32U-VI superalloy, derived by directional solidification from the melt in different temperature gradient are presented.
