摘要

Ceramic-particle-reinforced aluminum matrix composites (AMCs) obtain attractive specific properties, but their industrial utilization is often limited by metal casting-specific manufacturability issues. In foundry practice, cast AMC performance is frequently governed by melt quality and defect formation during particle addition, wetting, dispersion, and solidification. This review synthesizes casting-centric studies on: (i) reinforcement selection and addition routes (ex situ versus in situ); (ii) particle–melt interactions controlling wetting, clustering, settling/flotation, and interfacial reactions; and (iii) the coupling between melt-conditioning strategies and casting quality metrics such as porosity, inclusion content, segregation, and microstructural uniformity. Ultrasonic melt treatment (USMT) is reassessed from a metal casting perspective: although often reported to improve degassing and refinement, its effectiveness in particle-containing melts is field-limited and sensitive to boundary conditions, sonotrode degradation, and scale. Key methodological gaps affecting reproducibility are identified, and practical directions for industrial translation are outlined, emphasizing integrated melt-conditioning, in situ diagnostics, and statistically robust 3D characterization.
