We have synthesized thin films of (Ti1-xNbx) 2 AlC by combinatorial method on TiC (111) seed layers grown on c -axis sapphire (Al2O3) substrates at 900 °C using magnetron sputter. X-ray diffraction showed the films to be c -axis oriented and epitaxial, and films contained a minor secondary phase of (Ti,Nb)C, irrespective of stoichiometry. Most notably, Raman spectroscopy suggest a sizable increase in the elastic modulus in the Nb-rich region as compared to either of the end members.
