Effect of Alloying Element Zr on the Organization and Properties of TiZr Alloy for Dental Implants
摘要
A series of Ti-xZr alloys with Zr content ranging from 5% to 20% were prepared. The effects of Zr addition on microstructure, physical properties and corrosion behavior of the alloys were investigated. The phase, microstructure, hardness and corrosion behavior were characterized by X-ray diffraction, optical microscope, scanning electron microscope, universal material testing machine, Vickers hardness tester and electrochemical workstation. The results show that when Zr content is 20% or less, the Ti-xZr alloy has an α-Ti structure, and the microstructure of the alloy is refined with the addition of Zr content. Due to the solid solution strengthening of α-Ti, the addition of Zr is indeed conducive to the hardening of cp-Ti. Combining strength and plasticity, the Ti-15Zr alloy has the best mechanical properties, with a strength of 683 MPa and a plasticity of 11.52%, showing plastic fracture.
