Fabrication and compressive properties of directional porous titanium scaffold by freeze casting TiH2 powders

Porous titanium scaffold has been prepared by freeze casting of TiH2 aqueous slurry for the application of structural core of sandwiches, filters, heat exchangers and bones due to the directional lamellar structure. The effects of freezing temperature and solid content, which are decisive parameter in freezing casting process, on porous structure are revealed. As freezing temperature drops and solid content increases, the porosity ranges from...
