TNZS, TiO2/TNZS and HA/TNZS mixed powders were prepared by high-energy milling for 48 h and then were treated by cold pressing sintering. The morphologies and phase of the three kinds of mixed powders and the microstructure, composition, phase composition, pore characteristic and elastic modulus of these three kinds of TNZS based materials after cold-press sintering were investigated. Results show that the three kinds of mixed powders have undergone mechanical alloying after high-energy milling for 48 h. After sintering, the phase composition of TNZS is alpha-Ti and beta-Ti, that of TiO2/TNZS is alpha-Ti, rutile TiO2 and anatase TiO2 and that of HA/TNZS is alpha-Ti, beta-Ti, HA, Ti2O3, CaTiO3, CaO and TixPy. The surface composition of the three materials is uniform; their porosity is 2.466%, 5.030% and 13.027%, respectively; their elastic modulus is 64.00, 103.93 and 119.43 GPa, respectively.
