Test data for uniaxial creep on material U 720 carb at 750 Celsius

As a part of the overall test programme of FP5 HTR-M1 Project, JRC-IET performed a series of uni-axial creep and low-cycle fatigue (LCF) tests on the nickel based superalloy Udimet 720 material with the objective of assessing the effect of a specific HTR operating environment. Tests were performed on as-received, heavily carburized, decarburized, and thermally aged material. The heavily carburized state was achieved by exposure for 1000h at 950 Celsius in a 1.6 bar absolute Argon+2%CH4 atmosphere.

本数据集作为欧盟第五框架研发计划（Framework Programme 5，FP5）下高温气冷堆-M1（High Temperature Reactor-M1，HTR-M1）项目整体测试计划的组成部分，欧盟联合研究中心能源与交通研究所（Joint Research Centre Institute for Energy and Transport，JRC-IET）针对镍基高温合金Udimet 720开展了一系列单轴蠕变与低周疲劳（Low-Cycle Fatigue，LCF）测试，以评估特定高温气冷堆运行环境的影响。测试分别针对供货态、高渗碳态、脱碳态以及热老化态的该合金材料进行。其中高渗碳态材料通过将试样置于绝对压力1.6巴的氩气+2%甲烷气氛中，在950摄氏度下暴露1000小时制得。
