High Energy Milling (HEM)
Abstract: Al2O3/Ti2AlC composites were synthesized by high energy milling and hot-pressing at 1200C in a vacuum furnace with a pressure of 4.810-2 Pa, using Ti, Al and C powder as raw materials. The effect of sintering temperature on the reactions, phase composition and microstructure of the synthesized products were investigated.
