An ultrasonic grinding mill was designed. It permits to carry out simultaneously intensive ultrasonic, mechanical and cavitation treatments of powder materials that in turn leads to sharp acceleration of diffusion, mass-transfer processes and solid phase reactions due to crystallite size and structure changing. It was shown that meta-stable non-equilibrium solid solution (Cu+Ni+Fe, Fe+C), and crystalline structure transformed (Fe(4)N: fcc-hcp transformation) powders could be obtained for the much shorter time in compare with traditional mechanical alloying in planetary ball mill.
设计了一种超声研磨机。它能够同时对粉末材料进行高强度超声、机械和空化处理，由于微晶尺寸和结构的变化，这反过来又会导致扩散、传质过程和固相反应急剧加速。结果表明，与行星式球磨机中的传统机械合金化相比，在更短的时间内就可以获得亚稳态非平衡固溶体（Cu+Ni+Fe、Fe+C）以及晶体结构转变（Fe(4)N：fcc-hcp转变）的粉末。
