Method for simultaneously preparing TiSi2 and titanium silicon alloy

The invention relates to a method for simultaneously preparing TiSi2 and titanium silicon alloy, and belongs to the technical field of efficient resource comprehensive utilization of titanium siliconalloy materials. The method provided by the invention comprises the following steps: crushing a titanium silicon alloy material to obtain material particles A with a particle size of not more than 0.5cm; placing the material particles A in a high-purity graphite crucible, then placing the high-purity graphite crucible under the conditions of a temperature of 1500-1700 DEG C and pressure of 10-1 to 10-2 Pa, carrying out electromagnetic induction heating to melt to obtain an alloy melt A; placing the alloy melt at a temperature of 1500-1700 DEG C, electromagnetically stirring, and preserving heat under vacuum conditions for 1-3 h to obtain an alloy melt B; under electromagnetic stirring conditions, subjecting the alloy melt B to directional solidification phase separation, wherein the strength of an applied magnetic
