On single-phase B1 molybdenum carbide thin films prepared by the rf sputtering technique at substrate temperatures between 40 and 800/sup 0/C isochronous annealing and He-irradiation investigations were performed. The transition temperature to superconductivity T/sub c/, the lattice parameter a/sub 0/, and the specific resistivity rho were measured as a function of annealing temperature and fluence, respectively. Both during annealing and irradiation MoC/sub x/ behaves quite differently from typical refractory compounds such as NbC and NbN. During annealing T/sub c/ drops pronouncedly between 250 and 400/sup 0/C. The B1 structure transforms to ..gamma..-Mo/sub 2/C between 600 and 900/sup 0/C. During irradiation T/sub c/ rises slightly and then drops by only 0.5 K. The lattice parameter a/sub 0/ changes only by 0.2%.
