The self-diffusion of titanium-44 in TiCx (0.67≤x≤0.97) was studied in the temperature range 1920°–2215°C. The diffusion coefficients are composition independent and can be described by the expression DTi*=(4.36−2.34+5.02)×104 exp[−(176 400±3600)/RT] cm2/sec; titanium diffuses slower than the non-metal atom by a factor of approximately 104 in the temperature range investigated. The results support the concept of independent diffusion along the respective sublattice of each component.
