Isothermal compression of spray formed superalloy GH742y has been conducted on Gleebe−1500D hot simulation at the deformation temperatures ranging from 930°C to 1020°C where the strain rates have ranged from 0.01s−1 to 10s−1, and the height reduction of 50%. The effect of deformation temperatures and strain rates on the flow stress was analyzed with the true stress-true strain curve, and the hot deformation...
