Abstract:Two kinds of titanium foams with different pore structures were prepared by slurry method. The pore structure and morphology of titanium foam were observed by digital camera and scanning electron microscope. The mechanical properties and energy absorption properties of titanium foam were investigated by the static compression tests. The results show that the titanium foam prepared by slurry method inherits the structure of precursor, and has 3D net structure. The edge of titanium foam is not compact, on which there are many fine pores. Titanium foam is not sensitive to the strain rates, and the yield strength is in the range of 1.00MPa-2.38MPa at strain rate of 3×10-4s-1-1×10-2s-1.Titanium foam has the properties of absorbing energy, and the titanium foam of fine pore and coarse pore reaches can absorb the max energy of 0.78MJ/m3 and 0.22MJ/m3 respectively.
