Effect of heat-treatment on microstructure and high-temperature deformation behavior of a low rhenium-containing single crystal nickel-based superalloy

A low rhenium-containing [001] oriented single crystal nickel-based superalloy with different γ′ morphologies induced by various aging treatments was compressed from room temperature to 1000°C. All the single crystal samples with different γ′ morphologies exhibit anomalous yield behavior. The sample...

Beschreibung
Zusammenfassung:	A low rhenium-containing [001] oriented single crystal nickel-based superalloy with different γ′ morphologies induced by various aging treatments was compressed from room temperature to 1000°C. All the single crystal samples with different γ′ morphologies exhibit anomalous yield behavior. The sample first aged at 1180°C has the widest anomalous temperature domain and highest yield strengths. The sample first aged at 1000°C has the highest anomalous peak stress temperature.
