Embodiment 1
[0015] Raw material powder with a molar ratio of titanium:silicon:carbon:aluminum of 3:1:2:0.5 is mixed by ball milling in an agate ball mill in a nylon ball mill pot in anhydrous ethanol. After the obtained mixed powder is vacuum dried, it is unidirectionally pressed in a steel mold with a pressure of 100 MPa to form a compact with a cross-section of 35 mm×8 mm and a thickness of 8 mm.
[0016] In this embodiment, a vacuum furnace of model RXR4020 produced by Hefei Tianli Equipment Co., Ltd. is used to heat the compact at 1350°C for 180 minutes at an air pressure of 0.01 to 0.1 Pa. One high temperature treatment can obtain more than 1 kg of sintered products.
[0017] The resulting product was ground into powder in an agate mortar. The X'Perts PROSUPER X-ray diffractometer was used for component analysis, and the obtained X-ray diffraction pattern is shown in Figure 1. The analysis shows that the product contains titanium silicide and titanium carbide, and the volume content of t...
Embodiment 2
[0020] The raw material powder with the molar ratio of titanium:silicon:carbon:aluminum of 3:1:2:0.1 is mixed by ball milling in an agate ball mill in a nylon ball mill tank in anhydrous ethanol. After the obtained mixed powder is vacuum dried, it is unidirectionally pressed in a steel mold with a pressure of 100 MPa to form a compact with a section of 35 mm×8 mm and a thickness of 8 mm. The compact is kept at 1250°C for 180 minutes at an air pressure of 0.01 to 0.1 Pa.
[0021] The resultant product was ground into powder in an agate mortar, and it was found that the composition analysis using X’Perts PROSUPER X-ray diffractometer showed that the carbon-silicon intermetallic compound Ti 5 Si 3 , Titanium carbide silicide, titanium carbide and carbon.
[0022] When other processing parameters remain unchanged, and only the holding temperature is lowered to less than 1250°C, the content of titanium carbide silicide in the resulting product decreases sharply, and the titanium carbid...
Embodiment 3
[0024] The raw material powder with the molar ratio of titanium:silicon:carbon:aluminum of 3:1:2:0.75 is mixed by ball milling in an agate ball mill in a nylon ball mill tank in anhydrous ethanol. After the obtained mixed powder is vacuum dried, it is unidirectionally pressed in a steel mold with a pressure of 100 MPa to form a compact with a section of 35 mm×8 mm and a thickness of 8 mm. The compact is kept at 1450°C for 180 minutes at an air pressure of 0.01 to 0.1 Pa.
[0025] The resultant product is ground into powder in an agate mortar, and it can be known by using X’Perts PROSUPER X-ray diffractometer to analyze the composition, which contains titanium silicide, titanium carbide and carbon silicon intermetallic compound TiSi 2 .
[0026] When other processing parameters remain unchanged, and only when the holding temperature is higher than 1450°C, the content of titanium carbide silicide in the resulting product decreases sharply, and the intermetallic compound TiSi between...
