Abstract

The invention discloses a cutter material capable of improving bending strength. The cutter material is composed of 3.2%-3.7% of molybdenum, 15.42%-17.31% of titanium carbide, 5%-7% of a metallic bond, 0.8%-1.21% of nickel, 1.2%-1.5% of manganese and the balance iron, and the sum of the percentages of the components is 100%. The invention further discloses a preparation process of the cutter material. According to the cutter material capable of improving the bending strength, titanium carbide is adopted, the bending strength of the material can be improved, a twice sintering technology is usedfor adhering the titanium carbide, the service life of the material is prolonged, and the safety of the material is improved; and moreover, in the preparation process, the preparation method is simple, short in period and low in raw material powder cost, and has a good practical value.

Description

technical field [0001] The invention belongs to the technical field of cutting tool materials and preparation methods thereof, and in particular relates to a cutting tool material with improved bending strength, and also relates to a preparation method of cutting tool materials with improved bending strength. Background technique [0002] A cutting tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. Most of the knives are machine-used. Since the knives used in mechanical manufacturing are basically used to cut metal materials, "knives" are generally metal cutting tools. Knives for cutting wood are called woodworking knives. There is also a special category of cutting tools for geological exploration, well drilling, and mine drilling, called mine cutting tools. [0003] The material used to make knives must have high high-temperature hardness and wear resistance, necessary bending strength, impact toughness and chemical inertness, good...
