ABSTRACT
The present work is focused on the fabrication and investigation of microstructures copperbased TiC nanocomposites produced by mechanical milling in a high energy planetary ball mill. TiH 2 , carbon copper powders were used as starting materials which In-Situ reaction between occurs to form nanoparticles. mixture Cu–TiH –C milled for 12 h at 450 rpm Argon gas. Annealing treatment process 950 °C was applied as-milled composite enhance reaction. consolidation conducted spark plasma sintering under uniaxial pressing 70 MPa. Sintering procedure done 1000 5 min. results indicated that nanoparticles are formed after particles increased up higher temperature °C. Fracture surface sintered samples shows ductile mode. HR-TEM image showed crystal size about 10 nm sample hardness relative density increase when increasing temperature.
