Description

technical field [0001] The invention relates to the technical field of powder metallurgy, can be widely used in mechanical alloying to prepare alloy powder materials, and more specifically relates to a high-energy grinding machine for industrial production and scientific research and development and a method for using the same. Background technique [0002] Mechanical Alloying (MA) refers to the long-term intense impact and collision of metal or alloy powder between powder particles and grinding media in a high-energy ball mill or rod mill, so that the powder particles are repeatedly cold welded and fractured. A powder preparation technology that leads to the diffusion of atoms in powder particles to obtain alloyed powder; the method and equipment are simple, easy to produce, the material preparation is less restricted by the equilibrium phase diagram, the synthesis range is wide, and the prepared alloy powder With fine grain size and high energy, it provides alloy powder wi...

AI Technical Summary

Problems solved by technology

The high-energy grinding machine is the main equipment for mechanical alloying. Its basic process is to achieve the circulation of alloy powder particles through the collision and impact of the grinding medium and the continuous cold welding-breaking-re-cold welding-re-breaking repeated process; in this process, The continuous refinement of the microstructure of alloy powder particles will be accompanied by the generation of a large number of defects. The final nanoscale structure and a large number of defects greatly promote solid-state diffusion and reach the state of mechanical alloying at room temperature; while the common grinding machine Generally large-scale equipment is suitable for mass production, which is not conducive to small-batch and customized production; in addition, most of the existing small grinding machines have low energy, low degree of powder alloying, long alloying time leads to many impurities, and automation The degree is low, and the process parameter indicators are not standardized, which is not conducive to the later research and development and material preparation; in addition, most small grinding equipment increases labor costs
