Test data for uniaxial tensile on material ALLOY 800H irr at 850 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数据（creep rupture data），系为联邦德国及北莱茵-威斯特伐利亚州的高温反应堆项目（含直接循环氦气涡轮机项目、核工艺热项目与区域供热项目）所测得，旨在评定可在最高950℃服役工况下应用的候选结构合金性能。研究针对每种合金开展了多炉批次试验，并重点考察了服役环境对材料性能的影响：测试环境包括含氢、水蒸气、一氧化碳、甲烷等微巴级别微量杂质气体的氦气，以及甲烷重整混合气。试验过程中，上述测试气氛会导致试样发生渗碳（carburisation）现象。但数据分析结果表明，在各测试温度下，空气、不纯氦气及甲烷重整气氛下的应力断裂数据（stress rupture data）均处于同一离散带（scatterband）内。
