Preparation of Low Density Open-cell Aluminum Foam by Soluble Plaster Mould
Low-density open-cell aluminum foam was prepared using soluble plaster mold by infiltrating casting
and its compressive behavior was analyzed.The soluble plaster mold was prepared by using polymeric reticular sponge as matrix plate
and effect of addition of MgSO4 and bauxite on solubility and compressive strength of the plaster mold were investigated.The low density open-cell aluminum foams were made by pressure infiltration casting
and the processing parameters of pressure infiltration casting were determined.In addition
compressive experiments for prepared aluminum foams were conducted to understand its compressive behavior.The results indicate that three deformed regions such as elastic zone
plastic collapsing zone and densification zone are observed in the compressive stress-strain curves of the open-cell aluminum foams
and the plastic plateau zone of the curves is characterized by distinct fluctuations in fluid stress.
