The creep rupture behavior and the effects of oxidation on the creep strength of ASME T23 steel have been investigated. At 625 °C and 650 °C, a greater degradation of long-term creep strength was observed than expected from conventional master curv

C-B-Ti composite ceramic materials have some preferable properties including high melting point as the inner wall materials of nuclear fusion devices, but their thermal shock resistances are not well known. In this experiment, those materials were fa
