چکیده انگلیسی
In this study, the tensile properties of C-103 Nb based alloy were evaluated in the temperature range between room temperature (RT) and 1200 °C using Gleeble test system at the strain rate of 10â2 sâ1. The presence of well-defined serrations and temperature insensitivity of 0.2% yield strength confirmed the occurrence of dynamic strain aging (DSA) from RT to 1200 °C. However, the DSA was found to have predominant effect only up to 900 °C, beyond which dynamic recovery and oxidation influenced the tensile properties. Fractography revealed that the alloy had undergone intergranular fracture, which was attributed to the DSA in the temperature range of 600-900 °C and oxidation in the temperature range of 1000-1200 °C.
