基于铝热还原的低成本Ti-4.5Al-xMo-2Fe合金制备及Mo含量对性能的影响
Preparation of low-cost Ti-4.5Al-xMo-2Fe alloy based on thermite reduction and the effect of Mo content on its properties
摘要
Abstract
Titanium alloys are widely used in aerospace and marine engineering owing to their high spe-cific strength,excellent corrosion resistance,and good high-temperature stability.However,the conven-tional production routes are energy-intensive and costly,which limits their broader application.In this study,high-titanium slag and titanium dioxide were employed as raw materials,and a Ti-Al-based in-termediate alloy was first produced via aluminothermic reduction.After refining and composition ad-justment,a Ti-4.5Al-xMo-2Fe near-α titanium alloy was obtained.The effects of Mo content(0,1.5％,3％,4.5％)on the microstructure and properties were systematically investigated.The results show that this short-process method can successfully produce Ti-4.5Al-xMo-2Fe alloys with uniform microstruc-tures.With increasing Mo content,the lamellar α phase becomes significantly refined and β phase pre-cipitation is promoted,leading to increased hardness and density.After hot compression deformation,the alloy containing 3％Mo exhibits the best hot workability at 850℃,a strain rate of 0.01 s-1,and 50％deformation.关键词
