The project is on laser-induced methods for processing transition metal         carbides and nitrides.  These methods, based upon laser melting and             decomposition, will be used to produce layers of carbides and nitrides          of W and Ti.  By controlling the laser parameters and substrate                 variables, microstructures ranging from amorphous to polycrystalline            can be obtained.  The laser-induced chemical vapor deposition will be           used to form layers and powders of carbides and nitrides of W and Ti.           The chemical composition and stoichiometry of carbides and nitrides can         be controlled by adjusting partial pressures of constituent gaseous             species in the reaction chamber.  These materials will be characterized         using TEM/STEM, Auger, SIMS, and RBS techniques in terms of                     mircostructures, chemical composition, stoichiometry, and homogeniety.          Amorphous films of carbides and nitrides produced by laser-induced              photolytic decomposition are expected to have unique physical and               mechanical properties.  Selected films will be evaluated by                     microhardness and electrical resistivity measurements.  The variation           of resistivity with temperature will be studied as a function of                stoichiometry and microstructure for various films.
