Tape casting of porous titanium thin sheets from titanium hydride

Titanium thin sheets have been fabricated by tape casting using slurries based on titanium hydride powder. Titanium hydride is attractive because of its reduced cost with respect to pure titanium. Sheets of various thicknesses were tape cast, debinded, dehydrided and sintered. Porous sheets with even surfaces were obtained. Scanning electron microscopy observations of the polished cross-sections showed fine and uniformly distributed pores. Tensile strengths of up to 320 MPa have been obtained for sheets with densities close to 75% of theoretical density.
