证明了通过冲击波压制生产致密和集中的含有纳米尺寸的Al 2O 3的中间合金的可能性。讨论了激波过程的不同条件。给出了中间合金的表征数据。纳米结构的母合金具有高密度并且便于冶金处理。结果发现，使用这种具有纳米陶瓷颗粒的母合金有利于将颗粒引入到铝熔体中。将母合金引入熔体期间和之后进行的超声处理进一步导致强化纳米颗粒的均匀分布以及合金强度和延展性的提高。实验结果显示和讨论。
The possibility of producing dense and concentrated master alloys containing nanosized Al2O3 by shock-wave compacting is demonstrated. Different conditions of shock-wave process are discussed. The data of master alloys characterization are presented. The nanostructured master alloys have high density and are convenient for metallurgical handling. It is found that the use of such a master alloy with nanoceramic particles facilitates the particle introduction into the aluminum melt. The ultrasonic treatment performed during and after the introduction of the master alloy into the melt further leads to uniform distribution of strengthening nanoparticles and improvement of alloy strength and ductility. Experimental results are shown and discussed.
