What is the characteristic of powder metallurgy
We often use powder metallurgy technology to make new materials, then what are the characteristics of powder metallurgy?
Firstly, powder metallurgy technology can minimize the segregation of alloy composition and eliminate the coarse and uneven casting structure. It plays an important role in the preparation of high performance rare earth permanent magnets, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high temperature superconducting materials and so on.
Secondly, a series of high-performance non-equilibrium materials, such as amorphous, microcrystalline, quasicrystalline, nanocrystalline and supersaturated solid solution, are prepared. These high-precision materials have excellent electrical, magnetic, optical and mechanical properties.
Then the powder metallurgy technology can easily realize various types of composite, give full play to the respective characteristics of each group of source materials, can be said to be a low-cost production of high-performance metal matrix and ceramic composite technology.
In addition, powder metallurgy technology can achieve near net shape and automatic batch production, but also can effectively reduce the production of resources and energy consumption.
Finally, powder metallurgy technology can make full use of ore, tailings, steelmaking sludge, steel rolling scale, recycling waste metal as raw materials, is an effective material recycling and comprehensive utilization of new technology.
