On the Foamability of AlSi12 Precursors Prepared by High Velocity Compaction

High Velocity Compaction (HVC) has been proposed as a cost-effective method to prepare foamable precursors and the feasibility of the process has been demonstrated. The impact energy results a key parameter to control the final precursor density. Increasing values of impact energy leads to a continuous enhancement of performances in terms of maximum expansion and stability of the foam up to values comparable to those of commercial Alulight® precursors.
