On the Role of both Vacuum System and Initial Size on Fabrication of Aluminum-LECA Composite Foam

Abstract:

In this work the Aluminum-LECA composite foam was fabricated using the molten method. First, the LECA pellets were sieved in to three different sizes. The sieved LECA was placed on a regular and irregular form in to the mold cavity and then the molten aluminum was poured. The effect of LECA pellets as like as using vacuum system on filling the mold were also studied. Optical microscopy and scanning electron microscopy were used to study the pour morphology and the bonding of LECA and aluminum. The results show that using vacuum system can improve the fluidity of molten aluminum as like as the bounding with the LECA pellet and the aluminum matrix. It is also illustrated that with increase in the pellet size, the fluidity was increased. It was while that the orientation of LECA pellets has a significant influence on the fluidity. Keywords: Aluminum-LECA composite, fluidity, Vacuum system
