TiC-based ferro alloy is a high-quality impact-resistant and wear-resistant material with TiC as the hard phase and high manganese steel as the bonding phase. It has gained great popularity in industries such as cement, mining, metallurgy, construction, mechanical processing, and boiler manufacturing. It has become more and more widely used. It is estimated that the annual output of TiC-based high manganese steel-bonded cemented carbide inserts required for crushing hammer heads in China’s cement industry has reached nearly 1,000 t. Therefore, corresponding basic research is actively carried out to further It is very necessary to improve the strength and toughness of alloys.
The performance of the matrix high manganese steel in the TiC-based high manganese steel alloy determines the toughness and impact resistance of the alloy to a large extent. The standard process to improve the performance of ordinary cast high manganese steel is to carry out water toughening treatment. That is, first High manganese steel is heated to the austenite zone temperature and kept for a period of time, so that the carbides in the cast structure are basically dissolved into austenite, and then quenched into water and rapidly cooled to obtain a single supercooled austenite. Structure. This high manganese austenite can effectively harden independently under the conditions of strong impact abrasive wear, showing good wear resistance.
