微型试样测试，以评估机械性能，提供了一个新的机会，进行结构完整性评估的在役发电部件，通过删除只有非常小的体积的材料。在这项研究中，高温疲劳试验的P22钢进行了一些疲劳性能测定使用微型试样测试方法。通过微型试样和文献中报道的更成熟的标准尺寸试样测试确定的疲劳性能之间进行了良好的比较。
Miniature specimen testing to evaluate mechanical properties, presents a novel opportunity to undertake structural integrity assessments of in-service power generation components, by removing only a very small volume of material. In this study, high temperature fatigue testing of P22 steel was undertaken and a number of fatigue properties determined using a miniature specimen testing methodology. Good comparisons were observed between fatigue properties determined by miniature specimens and the more established standard-sized specimen testing reported in literature.
