The metal powder metallurgy is the preparation of metal or metal powder (or a mixture of metal powder and non-metallic powder) as a raw material, manufacturing technology of metal materials, composite, and all types of products forming and sintering. Powder metallurgy and production of ceramics is somewhat similar, so a series of new powder metallurgy technology can also be used for the preparation of ceramic materials. Because of the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials, plays an important role in the development of new materials.

Metal powder metallurgy technology can minimize the alloy composition segregation, the elimination of coarse, uneven casting organization. Corrosion resistance of stainless steel in the preparation of high-performance rare earth permanent magnetic materials, rare earth hydrogen storage materials, luminescent materials, rare earth catalysts, high temperature superconducting materials, new metallic materials (such as Al-Li alloy, heat-resistant Al alloys, super alloys, powder, powder The high-speed steel, intermetallic compounds, high temperature structural materials, etc.) play an important role.

The metal powder can be prepared amorphous, microcrystalline, quasicrystals, nanocrystalline supersaturated solid solution such as a series of high-performance non-equilibrium materials, and these materials have excellent electrical, magnetic, optical and mechanical properties. At the same time, the metal manganese powder can easily implement various types of composite, give full play to the characteristics of each group element material is a low-cost production of high performance metal matrix and ceramic composite materials technology. It also can produce the ordinary melting method can not be produced with a special structure and properties of materials and products, new porous biomaterials, porous membrane materials, high-performance structural ceramics and functional ceramic materials.

The metal power supplier can be achieved net near the formation of form and automated mass production, which can effectively reduce the production of resources and energy consumption. It can take advantage of the ore, tailings, and steelmaking sludge rolled steel scales, recycling scrap metal as raw material, is an effective material recycling and comprehensive utilization of new technologies. The development of powder preparation of new technologies, new processes, process theory, with emphasis on ultra-fine powder and nano-powders, rapid cooling of amorphous, quasicrystal and microcrystalline powders, mechanical alloying technology, self-propagating high temperature synthesis , powder size, structure, morphology, composition, control technology. The general trend is that controlled the direction of the ultra-fine, ultra-pure and powder characteristics.
