Abstract

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 coarse and fine matching is not needed, the process control is simple, non-professional workers can easily master the process, and the preparation difficulty is greatly reduced.

Description

technical field [0001] The invention relates to the field of hard alloys, in particular to a method for preparing a lightweight high-strength titanium-based fine-grain hard alloy material. Background technique [0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting Difficult-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel, and tool steel. Now the cutting speed of the new cemented carbide tool is hundreds of times that of carbon steel. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion ...
