Morphological Features of Microstructure of Samples Based on EP741NP Granulated Alloy Modified with Aluminum Nitride Nanoparticles

The effect of aluminum nitride nanoparticles on the microstructure of granulated heat-resistant nickel alloy EP741NP is considered. The analysis of the change in the morphology of carbonitride phases formed during heat treatment, their location in the volume of the material, and changes in the nature of the precipitation of γ' phase particles is carried out. The introduction of aluminum nitride nanoparticles allowed us to conclude that it has a promising possibility of its use as a modifier for nickel-based alloys.
