Lightweight high-strength titanium-based fine-grain hard alloy rod material and preparation process thereof

Abstract

The invention discloses a lightweight high-strength titanium-based fine-grain hard alloy rod material, made from, by weight, 15% of WC, 51.5% of TiC, 0.5% of Si3N4, 8% of Co powder, 10% of Mo powder,and 15% of Ni powder. The lightweight high-strength titanium-based fine-grain hard alloy rod material and a preparation process thereof have the advantages that the reasonable titanium content in theproduct formula provides ideally low overall compactness for the material, the grain size is small, and the overall product hardness is better; aggregation of powder particles of the material is avoided, and tissue distribution is uniform; rapid sintering is easy to perform during preparation, and harmful reaction with a binder is avoided; a tool made with the lightweight high-strength titanium-based fine-grain hard alloy rod material has the good characteristics such as good hardness, high strength, low weight, high wear resistance and long service life, and the tool well meets the processingrequirements for hard alloy bits, millers, alloy steel, titanium alloy and the like.

Description

technical field [0001] The invention belongs to the technical field of hard alloy materials, and in particular relates to a light-weight high-strength titanium-based fine-grained hard alloy rod material for cutting tools and its preparation process. The product is mainly used in cutting processing of various high-end equipment parts, machine The field of tool production for processing. Background technique [0002] In recent years, with the development of science and technology, the equipment manufacturing industry has developed rapidly, bringing major development opportunities to related supporting industries. As a manufacturer of special machining tools in the field of equipment manufacturing and cemented carbide rod materials for drill bits, it is also facing major development opportunities. However, opportunities are also accompanied by competition. Relevant industrial enterprises at home and abroad are also increasing their research on cemented carbide rod material tec...

Problems solved by technology

[0003] Although there are hundreds of large, medium and small cemented carbide manufacturing enterprises in China today, there are not many domestic enterprises that focus on the development of lightweight cemented carbide rod materials and technological breakthroughs, and most of the industry enterprises are in the middle and low levels. High-end level, compared with foreign countries, the gap is obvious

Enterprises in foreign industries pay more attention to technological innovation and product performance, especially in Europe, America, Japan and other technologically advanced regions, which have greater technological advantages and market competitive advantages. Representatives include Swedish SANDVIK, German KENNAHERTEL and TITEXPLUS and other well-known manufacturers in the industry, and many Domestic high-end equipment manufacturing knives manufacturers still prefer to import similar foreign products, which cost a lot and are not suitable for widespread use
