Abstract

In this work, a nanostructured TiC powders were produced by mechanical alloying (MA) through high energy ball milling from a mixture of elemental powders of titanium (Ti) and graphite (C) in argon atmosphere. MA process was performed for 20 h in a planetary ball mill (Fritsch Pulverisette 7) at room temperature at a ball-to-powder weight ratio of 70:1. Microstructure and morphology of the samples were investigated by using X-ray diffraction (XRD), laser granulometry, scanning electron microscope (SEM), and transmission electron microscope (TEM). XRD studies revealed that in the times more than 15 h of MA all the raw materials were changed to the desired materials. Results showed that nanocrystalline TiC, with about 10 nm, is synthetized by reaction between Ti and C atoms.
