摘要：

A low rhenium-containing [001] oriented single crystal nickel-based superalloy with different gamma' morphologies induced by various aging treatments was compressed from room temperature to 1000 degrees C. All the single crystal samples with different gamma' morphologies exhibit anomalous yield behavior. The sample first aged at 1180 degrees C has the widest anomalous temperature domain and highest yield strengths. The sample first aged at 1000 degrees C has the highest anomalous peak stress temperature. (C) 2014 Elsevier B.V. All rights reserved.
