Zusammenfassung:	The invention provides a preparation method of a light high-strength titanium-based fine-grain hard alloy material. The preparation method comprises the following steps that S1, raw materials including 20%-50% of WC, 20%-50% of TiC, 8%-15% of Co powder, 5%-20% of Ni powder, 3%-5% of Cr, 5%-10% of Fe powder and 2%-5% of Cu powder are prepared. According to the preparation method of the light high-strength titanium-based fine-grain hard alloy material, the overall density of hard alloy bar materials reaches a low ideal level, and the grain size is reduced, so that the overall hardness of the product is better; raw material powder particles are free of agglomeration and uniform in structure distribution, rapid sintering is easy in the preparation process, and harmful reaction with a binder isavoided; the hard alloy material has the excellent characteristics of good hardness, high strength, low mass, high wear resistance and long service life, and the toughness of hard alloys is guaranteed; and a mode of WC coars
