چکیده انگلیسی
Tensile properties of M951 alloy are shown to be significantly dependent on temperatures in this study. Like in other superalloys, the yield and tensile strengths decreased slightly between room temperature and 600 °C, then both strengths showed peak values at intermediate temperatures, and both decreased sharply above 850 °C. The elongation fluctuated with temperature with its minimum at 800 °C. The TEM observations showed that at low temperature the dominant deformation mechanism was γⲠshearing by dislocation pairs and slip bands. At high temperature, the deformation was dominated by γⲠby-pass. At intermediate temperature it showed a transition from γⲠshearing to by-passing.
