In order to obtain stress–strain curves of FGH96 powder at forming temperatures and strain rates, ideally it is necessary to conduct a uniaxial compression test on the single particle using nano-indentation, but in the present situation this technique is not available at a temperature over 900 1C. Therefore a compression specimen, with a length of 12.0 mm and a diameter of 8.0 mm, from fully dense HIPed material was used, which can be used to approximate the material properties of FGH96 single powder. Since the stainless steel container is deformed in the forging process as well, high temperature uniaxial compression tests were conducted for stainless steel and FGH96. Tests at temperatures of 900 1C, 1000 1C and 1150 1C and strain rates of 0.1 s1, 1.0 s1 and 10.0 s1 were performed using the computer-controlled thermo- mechanical simulator Gleeble 3800.
