Study on the Process for Fabricating Fly-ash Floating Beads Particle Reinforced Aluminum foam Matrix Composite

摘要

Fly-ash floating beads particle reinforced Al foam matrix composite was fabricated by stirring casting method. Orthogonal test method shows that main influence factors on the fabrication of Al foam matrix composite from big to small in proper order is foaming time, foaming temperature, and amount of foaming agent. The optimum preparation process condition is as following:the foaming temperature is 800°C, the amount of foaming agent is 3%, and the foaming time is 12 min.
