The effect of preform processing on replicated aluminium foam structure and mechanical properties

In replication processing of open-pore aluminium foams, the relative density can be varied by densifying the NaCl preform before infiltration. This can be done either by cold pressing or by sintering; we compare the two processes, show that the former yields superior foam modulus and flow stress, and explain why.
