- Abstract
Using carbamide granules as the pore-making agent, Zn-xMg alloys (x = 0 wt.%, 5 wt.%, 10 wt.%, 15 wt.%, 20 wt.%) foams with open-cell structures (porous Zn alloys) and porosity of 50 % were fabricated by means of reactive sintering powder metallurgy. The effect of Mg on the cell wall microstructures, compositions, and compression behaviors of porous Zn alloys were investigated. The results show that sintering at a temperature of 350°C can make Zn react with Mg to form intermetallics/solution, leading to effectively establishing the metallurgical bonding. When a proper Mg was added, the formed intermetallics are beneficial for improving the compression yield strength of porous Zn alloys, but too high Mg addition leads to compression strength decrease. The porous Zn-10 wt.% Mg alloy possesses the best compression property, whose compression strength is 12.4 MPa and Young's modulus is 0.332 GPa. The fabricated porous Zn alloys possess comparable mechanical properties with those of cancellous bones, whose compression strength and Young's modulus are 7–10 MPa and 0.259–0.332 GPa, respectively.
