THE HIGH TEMPERATURE LCF BEHAVIORS OF SUPERALLOY GH169
-
摘要: 本文详细地研究了镍基高温合金GH169在360，550和650℃的低周疲劳行为，其中包括循环应力-应变行为、玛辛特性和温度对GH169合金低周疲劳性能的影响此外，还对其低周疲劳寿命用塑性应变能W来表达作了探讨。Abstract: In this paper, the low cycle fatigue (LCE)behaviors of Ni-base supcrallcy GH169 were studied in detail at 360,550 and 650℃，including the cyclic stress strain behavior，Massing effect and the effect of temperature on LCP properties of alloy GH169. In addition, the LCE lives expressed by plastic strain energs w were also discussed.
