Powder metallurgy technology (1) can minimize segregation of alloy components and eliminate coarse and uneven casting structure. It plays an important role in the preparation of high-performance rare earth permanent magnet materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high-temperature superconducting materials, and new metal materials (such as Al-Li alloy, heat-resistant aluminum alloy, high-temperature alloy, powder corrosion-resistant stainless steel, powder high-speed steel, intermetallic compound high-temperature structural materials, etc.). ).
(2) A series of high-performance non-equilibrium materials such as amorphous, microcrystalline, quasicrystalline, nanocrystalline and supersaturated solid solution can be prepared, which have excellent electrical, magnetic, optical and mechanical properties.
(3) Various types of composite materials can be conveniently realized, and the respective characteristics of each component material can be fully exerted, which is a low-cost process technology for producing high-performance metal matrix and ceramic composite materials.
(4) It can produce materials and products with special structures and properties that ordinary smelting methods cannot produce, such as new porous biomaterials, porous separation membrane materials, high-performance structural ceramic abrasives, functional ceramic materials, etc.
(5) Near-net molding and automatic mass production can be realized, and production resources and energy consumption can be effectively reduced.
(6) It can make full use of ore, tailings, steel sludge, rolled steel scales and recycled scrap metal as raw materials, which is a new technology for effective regeneration and comprehensive utilization of materials.
Many of our commonly used processing tools and hardware abrasives are made by powder metallurgy technology.
