Small punch tensile/fracture test data for 2.25 Cr 1Mo V mod material at 25 °C and a displacement rate of .003 mm/s

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.本数据集源自一项旨在评估小冲杆（Small Punch, SP）试验方法可靠性的研究项目，该方法作为替代力学测试技术，用于评估老化工业装置中构件的剩余寿命与完整性。 试验采用的材料为2.25Cr-1Mo-V改性铁素体低合金钢，该材料广泛用于制造石化厂的高温构件。研究证实，该测试技术可同步获取材料的蠕变性能与拉伸性能参数。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蠕变测试技术在评估材料因氢腐蚀与热时效引发的性能劣化方面的应用潜力。
