Magnesium alloy micro-truss materials

This study developed a lost foam casting approach to fabricate Mg alloy micro-truss materials for the first time. Mechanical properties were evaluated in uniaxial compression and it was found that the peak compressive strength was controlled by the maximum shear stress that could be supported by the cellular struts. Significantly higher specific strengths were achieved than what has been previously reported for conventional Mg and Mg alloy foams.
