一种新型的，分层，多孔复合材料从一个单一的材料组成的颈缩粉末和熔融固体，具有可调的机械性能，制造电子束熔化和随后的热处理。该复合材料表现出低杨氏模量（约31 GPa）和优异的能量吸收能力，这两者对于骨科应用都是必要的。据我们所知，这是第一次报告的材料合成相结合的可控低杨氏模量和优异的韧性。
A novel, hierarchical, porous composite from a single material composed of necked powder and melted solid, with tunable mechanical properties, is fabricated by electron beam melting and subsequent heat treatment. The composite demonstrates low Young’s modulus (⩽31 GPa) and excellent energy absorption capacity, both of which are necessary for use in orthopedic applications. To the best of our knowledge, this is the first report on the synthesis of a material combining controllably low Young’s modulus and excellent toughness.
