Effect of Trace Oxygen Content on Microstructure and Mechanical Properties of Ti-3Zr Alloy AITranslate
Abstract AITranslate
The effect of trace oxygen content on phase transition temperature,microstructure and mechanical properties of Ti-3 Zr alloy was discussed by differential scanning calorimetry,X-ray diffractometry,metallographic microscope,transmission electron microscope,universal testing machine and Vickers hardness tester.The experimental results show that with the increase of oxygen content,the phase transition temperature of Ti-3 Zr-xO alloys increases,and their microstructure greatly changes,transforming from Widmanstatten structure into basket-waved structure,then into bimodal structure and finally into equiaxed structure.The tensile strength and yield strength of the alloys are significantly increased with the increase of oxygen,attributed to the solid solution strengthening of oxygen.The plasticity of the alloys shows a decline trend on the whole.Ti-3 Zr-0.05 O has lower plasticity than adjacent alloys due to the presence of a certain number of dislocation cells and ultrafine crystals in its substructure.The plasticity of Ti-3 Zr-0.25 O alloy is significantly improved by the toughening mechanism of nano-twin crystals.Ti-3 Zr-0.25 O alloy has the best comprehensive mechanical properties.
