Small punch creep test data for 2.25 Cr 1Mo V mod material at 560 °C and a load of 340 N (tenth repeat test)

Data collection created in the scope of a programme designed to evaluate the reliability of the Small Punch (SP) testing method as an alternative mechanical test technique for evaluation of the residual life and integrity assessment of components in ageing plants.
Tests were performed on the low alloy - 2¼Cr 1Mo V modified ferritic steel, widely selected for construction of high temperature components in petrochemical plants. The technique was shown to facilitate determination of both creep and tensile properties of materials. However, special attention was directed to the potential of the SP creep testing technique for assessing the deterioration of material due to hydrogen attack and thermal ageing, in comparison with conventional uniaxial creep methods.

本数据集依托一项旨在评估小冲杆（Small Punch, SP）试验方法可靠性的研究项目构建而成，该方法作为替代型力学试验技术，可用于评估老化服役装置中构件的剩余寿命与完整性。
试验以2.25Cr-1Mo-V改性铁素体低合金钢为试样材料，该材料广泛用于制造石化装置中的高温构件。研究表明，该技术可便捷获取材料的蠕变与拉伸性能参数。不过，相较于传统单轴蠕变试验方法，本次研究重点聚焦于SP蠕变试验技术在评估材料因氢腐蚀与热老化引发的性能退化方面的应用潜力。
