Abstract:

Microporous titanium was fabricated by a special powder metallurgy process and the microstructure and the mechanical properties of the material were characterised by scanning electron microscopy and quasi-static compression. The pore sizes and porosities of the samples are ranged of 10–50 μm and 40–65%, respectively. Macroporous Ti samples with the pore sizes ranged from 500 to 800 μm were also prepared by the similar process for comparison. The microporous Ti exhibits not only a very different deformation behaviour from the macroporous Ti but also lower flow stress than the latter, completely different from those observed in common porous metals.
