The effect of space holder content and sintering temperature of magnesium foam on microstructural and properties prepared by sintering dissolution process (sdp)

Abstract Magnesium foam has gained a significant interest in structural application due to low density and greater strength than aluminium foam. In this study, magnesium foam was produced by sintering dissolution process (SDP) using spherical carbamide as the space holder. Magnesium foam was prepared using SDP at sintering temperatures (600 'C, 630 0 C, 650 • C) and carbamide composition (30 wt.%, 50 wt.%, and 70 wt.%). The foams produced were characterized for morphology, density, porosity and compressive strength. Porosity of the magnesium foam increased with increasing amount of spacc holder at all the sintcring temperatures while the density showed thc rcverscd trend. Magncsium foam with 50 wt.% carbamidc at all the sintering temperatures showed the acceptable range of density and porosity for energy absorbent which are in the range of 0.57-0.61 g/cm3 and 64.7-67.3%. Magnesium foam with 50 wt.% carbamide at sintering temperature of 630 0 C has density, porosity and compressive strength of 0.61 g/cm3, 64.7% and 5 MPa.
