PRODUCTION AND CHARACTERIZATION OF Al – WC COMPOSITE POWDERS VIA MECHANICAL ALLOYING
Machines. Technologies. Materials., Vol. 9 (2015), Issue 12, pg(s) 34-37
Mixtures of 10, 20 and 30 wt. % of tungsten carbide powder and aluminum powder were ball milled for 2, 4 and 8 hrs to investigate the effect of percentages of the reinforcement and mechanical alloying time on microstructural properties of the produced composite powders. Finer particles were tried to obtain in ductile matrix. The milled powders were analyzed using X-ray diffraction (XRD).
Nano/micro particle size and distribution (PSD) technique was used to measure particle size and distribution. Scanning electron microscopy (SEM) was also performed to observe particle morphology.
