对喷雾雾化和共沉积法制备的颗粒增强金属基复合材料的微观结构和力学性能进行了严格的研究，特别强调了陶瓷相对所得微观结构的影响。重点介绍了室温和高温铝合金的最新研究结果，并参考现有动力学和热力学模型的预期结果，讨论了喷射沉积过程中SIC颗粒与凝固前沿的相互作用。此外，在喷射沉积过程中，当陶瓷颗粒的分布被共同注入金属喷雾中时，通常观察到的晶粒尺寸减小，通过考虑热能传递等因素来合理化。

THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF PARTICULATE REINFORCED METAL MATRIX COMPOSITES PROCESSED BY SPRAY ATOMIZATION AND CO-DEPOSITION ARE CRITICALLY EXAMINED, WITH PARTICULAR EMPHASIS ON THE EFFECTS OF THE CERAMIC PHASE ON THE RESULTING MICROSTRUCTURE. RECENT RESULTS OBTAINED WITH BOTH ROOM AND ELEVATED TEMPERATURE ALUMINUM ALLOYS ARE HIGHLIGHTED, AND THE INTERACTION OF THE SIC PARTICULATES WITH THE SOLIDIFICATION FRONT DURING SPRAY DEPOSITION IS DISCUSSED, IN REFERENCE TO THE RESULTS ANTICIPATED FROM AVAILABLE KINETIC AND THERMODYNAMIC MODELS. IN ADDITION, THE DECREASE IN GRAIN SIZE WHICH IS NORMALLY OBSERVED WHEN A DISTRIBUTION OF CERAMIC PARTICULATES IS CO-INJECTED INTO A METALLIC SPRAY DURING SPRAY DEPOSITION IS RATIONALIZED BY CONSIDERING, AMONG OTHER FACTORS, THE TRANSFER OF THERMAL ENERGY.
