Effects of TiC Additions on Physical Properties of W-2wt.%VC-1wt.%C

Effects of TiC additions on physical properties of W-VC-C nano powder composites during different milling time were investigated. W-2wt.%VC-1wt.%C and W-2wt.%VC-2wt.%TiC-1wt.%C composite powders were mechanically alloyed (MA’d) for 1 h, 3 h, 6 h, 12 h and 24 h in a high energy ball mill. Characterization studies were conducted to determine the effect of TiC content and MA duration on the morphology, lattice parameter, crystallite size and lattice strain amorphization rate of the powder composites. Addition of TiC declined particle size decreasing rate and powder densities after MA for 24 h. Both Gaussian and Williamson Hall (W-H) methods were employed on the X-ray diffraction patterns to analyse the variations of lattice strain (
