Preparation of Al Foam Sandwiches and Analyzing on the Interface Solidification Microstructure

Abstract:

Al Foam Sandwiches (AFS) has been created by a process of hot pressing Al-TiH2 precursor (core) made by cold pressing together with steel sheet, and then foaming. The microstructure and composition of Al-Fe interface has been analyzed by SEM and Element Linescanning Electron Microscopy (ELEM). The experiment and analysis show that during hot pressing process, firm mechanical bonding is formed between steel sheet and core, during foaming, the intermetallic compound FeAl3 and eutectic structure (FeAl3+Al) were formed by diffuse of Fe and Al elements each other at the interface, which gave a rise to a good metallurgical bonding interface between sheet and core.
