Fabrication of High-Content Ti3AlC2 Powders by Mechanical Alloying

摘要：

　　In the present study,high-content Ti3AlC2 ceramic powders were fabricated by mechanical alloying (MA) using the Ti,Al and C as the starting materials.And the effect of Al content on the formation of Ti3AlC2 was investigated.The results showed that the large-sized granules were obtained to coexist with the powders after ball milling of 3Ti/Al/2C powder mixtures for 3 h.Ti3AlC2 in the synthesized powders is the main phase based on the XRD analysis.For the composition of 3 Ti/1.1 Al/2C,high-content Ti3AlC2 powders (87.6 wt.%) have been obtained after milling for 3h.Excessive Al,however,would reduce the content of Ti3AlC2 in the products.
