摘要：

Elemental powder mixture of titanium, tungsten and graphite is milled by high energy planetary ball mill at a fixed ball to powder mass ratio (BPMR) for different duration to produce nanosized particles of Ti0.9W0.1C hard metal. Microstructure characterization in terms of lattice imperfections and phase quantification of ball-milled samples has been done primarily by analyzing the XRD pattern and employing Rietveld method of structure and microstructure refinement. After 8 h of ball-milling full formation of Ti0.9W0.1C is noticed without any contamination of other phase or milling media. TEM study of 8 h ball-milled sample gives direct supportive evidence of structural and microstructural evaluation by XRD pattern analysis. A comparative study of microstructural changes between TiC and Ti0.9W0.1C helps to understand the effect of addition of W as solute in Ti-C metal matrix. (C) 2013 Elsevier B. V. All rights reserved.
