Abstract

The nature of stability of dendritic microsegregation of rhenium in single crystals of intermetallic (γ′ + γ) alloys based on γ′-Ni₃Al is determined under a high-temperature heat treatment and under creep and endurance tests. It is assumed that steady dendritic microsegregation of rhenium is a factor determining the high high-temperature strength of rhenium-containing (γ′ + γ) alloys based on γ′-Ni₃Al.
