Development of titanium foams as an implant with low Young's modulus has brought the scientific and technological attention. Titanium based alloys were produced by mechanical alloying using a planetary mill. This work study the effect of Manganese (Mn) on mechanical properties in compression of Ti-13%Ta-30%Nb-x%Mn (x: 2 and 6 wt.%) foam. Foams were obtained using ammonium hydrogen carbonate (50%v/v) as space-holder with a mean particle size of 35 μm. Powders and space-holder were mixed and uniaxial pressing was performed at 430 MPa of compaction pressure. To remove the space holder from the matrix the green compacts were heated to 180°C for 1.5 h and sintered at 1300°C for 4 h in Ar atmosphere. The Young?s Modulus of this foam is smaller when compared with pure Ti , and the yield strength is increased with the amount of Mn increases. Finally, the Gibson-Ashby, Meyer and Nielsen Models were applied to predict the mechanical properties of titanium foams.
