摘要：
Effcts of neutron irradiation on the physical properties of light transition metal carbides, TiC(x), VC(x) and NbC(x), were examined, emphasizing the characterization of irradiation induced defects in the nonstoichiometric composition. TiC(x) irradiated with 14 MeV (fusion) neutrons showed higher damage rates with increasing C/Ti (x) ratio. A brief discussion is made on "cascade damage" in TiC(x) irradiated with fusion neutrons. Two other carbides (VC(x) and NbC(x)) were irradiated with fission reactor neutrons. The irradiation effects on VC(x) were not so simple, because of the complex irradiation behavior of "ordered" phases. For instance, complete disordering was revealed in an ordered phase, "V8C7", after an irradiation dose of 10(25) n/m2.
