摘要	Temperature dependence of the tensile behavior of a Fe-based gamma' strengthened austenitic alloy was investigated from 25 to 900 degrees C. The stress-stain curves and the microstructures after deformation were studied. The results showed an abnormal tensile behavior with increasing temperature. Serrated stress-strain curves were observed in the samples deformed at temperatures from 300 to 700 degrees C. Microstructure observation on the deformed samples shows that twins formed during deformation at 300 to 700 degrees C and became profuse at 700-800 degrees C. Those twins had a predominant effect on the deformation mechanisms at high temperatures. (C) 2007 Elsevier B.V. All rights reserved.
