Mechanical, acoustic and electrical properties of porous Ti-based metallic glassy/nanocrystalline composites
Highlights ► We synthesize porous Ti-based metallic glassy/nanocrystalline composite. ► Porous composite has high fracture strength and strong energy absorption ability. ► Wave absorption ability of the composite can be enhanced by increase the porosity. ► A desired electrical property can be obtained by change the porosity of composite.
Abstract The porous Ti-based metallic glassy/nanocrystalline composites were synthesized using powder metallurgy route. The sintered samples with different porosities can be obtained at sintering temperatures below glass transition temperature. The properties of the samples directly depend on the porosities and the sintered porous samples combine mechanical and acoustic properties of the porous crystalline material and the metallic glass, e.g. high strength, strong wave and energy absorption ability. Furthermore, the fundamental electrical behavior for this kind of novel porous material was also studied based on the percolation theory model, which helps to design and fabricate porous composites with unique electrical property. Our results suggest that the sintered porous composites have potentials for structural and functional applications.
