Microstructure characterization of mechanosynthesized nanocrystalline metal carbides

The need of improved materials in high temperature structural applications has stimulated research into the mechanical behavior of a number of materials including the refractory hard metals. This study presents the microstructure characterization of nanocrystalline binary/ternary metal carbides synthesized by mechanical alloying (MA) of different metals and graphite powders. The high-resolution electron microscopy study of final ball-milled sample in each case gives direct supportive evidence of structural and microstructural evaluation by XRD pattern analysis.
