| Abstract: | Corrosion resistivity in Hank's artificial body fluid, compression strength and hardness for heterogeneity Ti-Fe-Mo-Mn-Nb-Zr alloys were investigated. The alloys whose compression strength and hardness of approximate to that of dentin were obtained. Considering cost, mechanical performances and corrosion resistivity of alloy, the relationship between component and hardness of titanium alloys was found by BP algorithm. The theoretical analysis agree well with experiment result. The element contents of alloys were optimized by the BP arithmetic in order to save valued elements with appropriate mechanical performances. |
