XRD patterns for different compositions of thin films grown on TiC (111) seed layers show textured growth in the (001) orientation. A minor secondary phase of (Ti,Nb)C was observed in most films.
-axis lattice constant of as a function of Nb concentration. The end points are the bulk values. No miscibility gap is observed.
Coefficient of friction as a function of Nb concentration. Overall the friction does not appear to be affected by substitution.
Raman spectra for various thin films of . Markers indicate the positions of vibrational modes as a function of Nb concentration. The lines serve as a guide for the eye.
