Characterization of titanium foams sintered at different temperatures prepared by the slurry method

The mechanical and physical propertics of titanium foam sintered at different temperatures are reported in this paper. In this work, the slurry method has been used for the production of titanium foams using pure titanium and titanium alloy (Ti6Al4V). The titanium slurry was first prepared by mixing...
