In the current studies, Hastelloy C-276, in as-received (forged) and solution treated conditions are subjected to thermomechanical treatments to evaluate the hot deformation characteristics. High temperature compression tests are performed in Gleeble 3800, a thermomechanical simulator, in the temperatures of 900-1200<sup>o</sup>C and at the strain rates of 0.001-10s<sup>-1</sup>. Processing maps are drawn using dynamic material model to determine the safe regions of hot workability. It was observed that as-received samples showed large stability regions compared to solution treated ones. In both cases, the maximum power dissipation efficiency was recorded at strain rates of 0.001-1s<sup>-1</sup> and temperatures of 1050-1200<sup>o</sup>C. The effect of dynamic recrystallization and resulting texture evolution on mechanical behavior was studied using X-ray diffraction, EBSD and TEM respectively.
