Test data for uniaxial tensile on material ALLOY 800H irr at 600 Celsius

The creep rupture data in this collection were determined for the high temperature reactor projects (the direct cycle helium turbine project, the nuclear process heat project and the district heating project) of the Federal Republic of Germany and the State of North Rhine Westphalia, the aim being to qualify the candidate constructional alloys for service at temperatures up to 950°C. Several batches of each alloy were investigated and special attention was given to the effects of the service environments (helium containing different impurity gases, such as hydrogen, water vapour, carbon monoxide and methane, all at microbar levels, and methane reforming gas mixture) on the properties. In the test machines, these test environments led to carburisation of test pieces. However, analysis of the data showed that the stress rupture data for tests in air, in impure helium and in methane reforming gas lay in the same scatterband at each temperatures tested.

The data were used for the formulation of draft nuclear design rules for the high temperature reactor systems, which are summarised in 'Proceedings of the Workshop on Structural Design Criteria for HTR', G Breitbach, F Schubert, H Nickel, Jül-Conf-71, April 1989, Berichte der Kernforschungsanlage Jülich GmbH, ISSN 0344-5798.

本数据集收录的蠕变断裂（creep rupture）数据，是为德意志联邦共和国及北莱茵-威斯特伐利亚州的高温堆（High Temperature Reactor, HTR）项目（直接循环氦气轮机项目、核工艺热项目以及区域供热项目）测定所得，旨在完成候选结构合金在最高950℃工况下服役的合格性评定。研究团队针对每种合金开展了多炉批次的试验，并重点考察了服役环境（含氢、水蒸气、一氧化碳、甲烷等微巴量级微量杂质气体的氦气，以及甲烷重整混合气）对材料性能的影响。在试验设备中，上述试验环境会导致试样发生渗碳现象。然而数据分析显示，在各试验温度下，于空气、不纯氦气及甲烷重整气氛中开展试验所得的应力断裂（stress rupture）数据，均处于同一离散带范围内。
