Abstract

Closed-cell aluminum foam was manufactured from preformed Al-TiH2 composite which was produced through ARB (Accumulative Roll Bonding) process. The effect of number of ARB cycles on distribution of TiH2 particles in aluminum matrix is investigated. It is observed that severe plastic deformation during high number of ARB cycles, leads to a homogenous distribution of TiH2 particles. This is due to increase in TiH2 containing interfaces and crumble of particles along the rolling direction. It is also shown that the TiH2 containing interfaces experience remarkable bonding quality in the last ARB cycles. Closed-cell foam was fabricated by annealing of preformed composite at appropriate temperature. It is observed that the number of ARB cycles and the foaming temperature, have considerable effect on porosity and cell morphology of produced foam.
