| Abstract: | A fabrication process for pressurized creep tubes (PCTs) for a highly purified V-4Cr-4Ti alloy, NIFS-heat2 was established. No increase in impurity contents in PCTs was detected during the tube manufacturing process. In a preliminary thermal creep test, homogeneous deformation was observed over entire tube length, which verifies reliability of creep measurement by using the present PCTs. |
