本研究首次发展了一种消失模铸造法制备镁合金微桁架材料。在单轴压缩中评价机械性能，发现峰值压缩强度由蜂窝状支柱可支持的最大剪切应力控制。实现了比先前报道的常规镁和镁合金泡沫显著更高的比强度。
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.
