W-Re/Cr Cosegregation Enhanced Thermodynamic Stability and Cohesion of the γ-Ni/γ′-Ni₃Al Phase Boundary

The thermodynamic instability and relatively low mechanical strength of γ/γ′ phase boundaries in Ni-based single-crystal superalloys compromise the service safety of these materials. The interfacial segregation behavior of alloying elements is expected to enhance the thermodynamic stability and mech...
