抄録	Ni-base wrought alloy HASTELLOY X tube was exposed to Ar-CH4 at 800 and 1000℃ in order to understand the carburization kinetics of the alloy used for fuel injection nozzles of micro-gas turbine combustors. Three different internal carbides, (Cr,Mo)3C2, (Cr,Mo)7C3 and (Cr,Mo)23C6 were observed in this order from the surface, and the partial damage to the outer surface of the specimen tube appeared similar to metal-dusting. The internal carburization kinetics on both the inner and outer parts of tube followed the parabolic rate law. The carbon permeability in HASTELLOY X was obtained, and was slightly smaller than that of Ni-20%Cr.
