Abstract

Abstract: Biaxial load was applied on the tube specimen by the inert gases medium, the inner pressure creep property of domestic Mo-3Nb alloy single crystal were studied. Up to now, the creep experiment has been done at 1600°C for 3000hours under three kinds of hoop stress. The three kinds of hoop strees is 5MPa,10MPa and 15MPa. Ultimately the creep curves under different conditions were obtained. The steady-state creep rate and the stress exponent in the Sherby-Dorn function have been deduced out. The stress exponent of Mo-3Nb is 5.4. Compare with the Russian single crystal, the creep property is close to Russian''s. [Copyright &y& Elsevier]
