Effect of Heat Treatments on the Microstructural Evolution of a Single Crystal High-Entropy Superalloy

Effect of Heat Treatments on the Microstructural Evolution of a Single Crystal High-Entropy Superalloy

The effect of solution heat treatment as well as primary and secondary aging treatment conditions on the microstructural evolution of a high-entropy superalloy was investigated. The as-cast sample shows coarsened γ′ precipitates and other extra phases at interdendrite region due to microsegregation....
