Abstract

The invention discloses a method for in-situ integrated preparation of a Ti (C, N)-based metal ceramic cutter material with high heat resistance, and belongs to the technical field of novel metal ceramic materials. The method comprises the following steps that 1) nanocrystalline AlxCoCrFeNiTi high-entropy alloy binding phase powder is prepared; 2) reaction raw materials are subjected to proportioning and mixing, and a Ti (C, N)-TiB2-AlxCoCrFeNiTi metal ceramic mixture is prepared; 3) a cutter mixed green body is prepared; and 4) the cutter mixed green body is placed in an atmosphere sintering furnace to be fired into a cutter sample. The Ti (C, N)-based composite metal ceramic material prepared through the method has a Ti (C, N) and TiB2 double 'core-ring ' structure, is compact and uniform in grain structure distribution, can be used for efficient machining of high-strength and other difficult-to-cut materials, and achieves industrial application of cutters.

Description

technical field

[0001] The invention belongs to the technical field of new cermet materials, and specifically relates to an in-situ integrated preparation of Ti(C,N)-TiB used in severe environments such as high-strength structural steel cutting with high temperature and high speed. 2 -Al x CoCrFeNiTi cermet tool material method. Background technique

[0002] In recent years, my country's aviation industry and heavy machinery manufacturing industry have achieved rapid development. They have shifted from purely relying on foreign technology to independent innovation, and from purely relying on purchase to independent design and manufacturing. As an important component in the manufacturing process, it requires materials with high reliability, good strength and toughness, and certain corrosion resistance. High-strength steels such as 15-5PH martensitic precipitation-hardening stainless steel, 1Cr18Ni9Ti stainless steel, and 69111 stainless steel have excellent mechanical prope...
