J0310303 スモールパンチクリープ試験による低合金鋼溶接継手のクリープ損傷評価
詳細
The effect of sampling location on SPC(Small Punch Creep) tests were investigated for weld joints to establish evaluation method of TypeIII and Type IV creep behavior. The SPC specimen shape was 10mm diameter and 0.5mm thick round disc prepared from weld joints of 2.25Cr-1Mo low alloy steel. It was found that the center of SPC specimen should be 1mm apart from the weld interface for Type III creep damage evaluation and 2mm apart from the weld interface for TypeIV creep damage evaluation as the recommended sampling location.
