在轻金属熔体中引入非金属颗粒是制备高性能金属基复合材料（MMC）技术中首先要克服的主要瓶颈。第二个瓶颈是这些颗粒在液体中以及最终在固体基质中的均匀分布。已知施加到液体/颗粒混合物的外部场有助于颗粒的润湿、混合和分布。综述了熔体强剪切和超声空化技术在铝基复合材料制备中的应用。讨论了其机理并给出了实例。介绍了一个新的欧洲项目ExoMet（EC grant 280421）在液态金属处理中外场应用的前景。
Introduction of nonmetallic particles to the melt of light metals is the main and first bottleneck to overcome in the technology for producing high performance metal matrix composites (MMC). The second bottleneck is the uniform distribution of these particles in the liquid and, eventually, the solid matrix. External fields applied to the liquid/particles mixture are known to facilitate wetting, mixing and distribution of the particles. This paper gives an overview on the application of intensive melt shearing and ultrasonic cavitation to the technology of MMC based on aluminum. The mechanisms are discussed and examples are given. The outlook of a new European program on the application of external fields in liquid metal processing ExoMet (EC grant 280421) is presented.
