摘要: Abstract The small-punch (SP) test and the SP creep were carried out by using a further miniaturized plate-type specimen (3 mm diameter × 0.25 mm thick). Those tests applied to electron-beam welded joint of reduced-activation ferritic steel for evaluating distribution high-temperature strength in joint. experimental results revealed that maximum load measured at 873 K was very similar obtained from Vickers hardness, fusion zone relatively devoid ductility. In addition, ratio stress standard uniaxial calculated so both rupture curves overlapped convert into those test. As result, determined be 0.43 base metal this load-stress conversion coefficient is good agreement with finite element analysis.
