| 摘 要： | Ti3SiC2 materials have been fabricated by spark plasma sintering of the elemental powders with the addition of Al.At the heating rate of 80℃/min and under the pressure of 30MPa,the ideal synthesis temperature of Ti3SiC2 is in the range of 1150-1250℃.The addition of Al is in favor of the formation of Ti3SiC2.The synthesized compound has the molecular of Ti3Si0.8Al0.2C2 and lattice parameters of α=0.3069nm,c=1.7670nm.Its grain is plane-shape with a size of about 50μm in the elongated dimension.The prepared material has Vickers hardness of 3.5-5.5GPa(at 1N and 15s) and is as readily machinable as graphite‘s.

| Abstract: | Ti3 SiC2 materials have been fabricated by spark plasma sintering of the elemental powders with the addi-tion of Al. At the heating rate of 80 ℃/min and under the pressure of 30 MPa, the ideal synthesis temperature ofTi3 SiC2 is in the range of 1 150 - 1250 ℃. The addition of Al is in favor of the formation of Ti3 SiC2. The synthesizedcompound has the molecular of Ti3 Si0.8 Al0.2 C2 and lattice parameters of a = 0.306 9 nm, c= 1.767 0 nm. Its grain isplane-shape with a size of about 50μm in the elongated dimension. The prepared material has Vickers hardness of 3.5 - 5.5 GPa(at 1 N and 15 s) and is as readily machinable as graphite's. |
