摘要：

Two kinds of titanium foam with different pore structures were prepared by a 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 the slurry method inherits the structure of precursor, and has a 3D net structure. The edge of titanium foam is not compact, on which there are many fine pores. Titanium foam is not sensitive to strain rates, and the yield strength is in the range of 1.00 similar to 2.38 MPa at strain rate of 3 X 10(-4)similar to 1 X 10(-2)s(-1). Titanium foam has the properties of absorbing energy, and the titanium foam of fine pore and coarse pore can absorb the max energy of 0.78 and 0.22 MJ/m(3), respectively.
