Lightweight Metals › Aluminum

In order to take advantage of the very good properties of Al alloys, the quality of ingots, billets, and components must be increased while maintaining low costs. Thus, various processes that include melting, solidification, alloy development, and fabrication are considered in this thrust area. Understanding the cooling conditions and their effect on microstructure evolution during solidification, defect formation, and defect growth is sought for various processes such as direct chill-casting process, sand casting, permanent mold casting, and die-casting. Understanding the complex relationships between microstructure and corresponding component properties is very important to the advance of aluminum technology.
