摘要

We report the synthesis of a new class of Al2O3-WC nanocomposites for the first time by using metal-organic chemical vapor deposition process in a spouted bed followed by spark plasma sintering technique. The microstructure and mechanical properties of these prepared nanocomposites have been analyzed for various sintering parameters. From microstructure observation, it is found that the nanosized WC particles are dispersed within alumina matrix grains and intergrains. The microstructure of transgranular and step-wise fracture surface are found in these nanocomposites. The basic mechanical properties like density, hardness, and toughness also have been analyzed and the results are interpreted by correlating with that of corresponding microstructures.
