| Abstract: | In this paper, low cycle fatigue testing on Nickel base superalloy GH536 were performed at three different temperatures(600℃, 700℃, 800℃).The strain life and cyclic stress strain relationship were given at various temperatures. The change in fatigue life behavior and fatigue parameters with temperature was discussed. At low and intermediate total strain amplitudes, the fatigue life was found to decrease with the increasing of temperature. |
