摘要
对镍基合金 GH5 36材料在三种不同温度下的低循环疲劳特性进行了研究。给出了材料的应变 -寿命关系和应力应变关系。讨论了材料的疲劳特性随温度的变化。结果表明 ,在中等应变幅值之下 。
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.
