High cycle fatigue test data for A-286 ph sa material at 20 °C

The FP7 project "In Space Propulsion 1" was set up to improve the fundamental knowledge and the techniques which are necessary to allow Europe to implement new ambitious space programs involving cryogenic propulsion. It concentrates on liquid oxygen, liquid hydrogen, and liquid methane propellants, and the anticipated progress will address - LOX methane combustion - heat and propellant management - materials tribology, compatibility, and hydrogen embrittlement. The data included here were generated in the part of the project relating to hydrogen embrittlement. In a frist step, materials of interest were screened through a literature research and by carrying out tensile tests in gaseous hydrogen (GH2) and Ar. Finally, two alloys (Inconel 718 and A-286) were selected as being the most interesting for the actual test campaign. For these two materials the influence of hydrogen on the fatigue behaviour in High Cycle Fatigue (HCF) tests was studied in high pressure GH2 and Argon.

FP7项目"In Space Propulsion 1"旨在提升基础理论知识与关键技术，助力欧洲实施涉及低温推进（cryogenic propulsion）的新型高难度航天计划。该项目聚焦液氧、液氢及液甲烷推进剂，预期进展将涵盖以下方向：液氧（LOX）-甲烷燃烧、热与推进剂管理、材料摩擦学、相容性及氢脆（hydrogen embrittlement）。本数据集包含项目中与氢脆相关部分产生的数据。首先，通过文献调研及在气态氢（GH2）与氩气（Ar）环境下开展拉伸试验，对目标材料进行筛选。最终，选取两种合金（Inconel 718与A-286）用于实际试验。针对这两种材料，研究了高压气态氢（GH2）与氩气环境下，氢对其高周疲劳（High Cycle Fatigue，HCF）行为的影响。
