The application of ultrasonic melt treatment to the production of natural and synthesized aluminum-based composite materials is considered in terms of underlying basic ideas and commercial implementations. It is shown that the ultrasonic cavitation treatment combined with microalloying of hypereutectic Al-Si natural composites (alloys) promotes the formation of structures suitable for further deformation. The use of highly impure starting materials becomes also possible. The combination of ultrasonic cavitation treatment with electromagnetic stirring allows one to considerably improve the size and spatial distribution of ceramic particles in metal-matrix composites.
从基本原理和商业应用的角度考虑了超声熔体处理在天然和合成铝基复合材料生产中的应用。结果表明，超声空化处理与过共晶Al-Si天然复合材料（合金）的微合金化相结合，促进了适合进一步变形的组织的形成。使用高纯度原材料也成为可能。超声空化处理与电磁搅拌相结合，可以显著改善金属基复合材料中陶瓷颗粒的尺寸和空间分布。
