由CMRT實驗室發展出的Ti-7.5Mo 合金於1999年通過美國專利申請(U.S. Patent No. 6409852)，為一深具實用潛力的鈦合金。本研究對Ti-7.5Mo合金進行不同的熱機處理，藉以探討其對機械性質，微觀結構與析出相的影響。
實驗結果顯示、Ti-7.5Mo合金經過熱滾壓，再進行T1℃固熔熱處理t1後，合金結構為細針狀麻田散鐵的外觀，主要的相屬介穩的α”相。其彎曲彈性模數為55GPa，拉伸彈性模數為70GPa。微結構，主要相與機械性質皆相近於鑄造Ti-7.5Mo合金。
Ti-7.5Mo經過熱滾壓後，然後進行T1℃固熔熱處理t1後，再進行T3℃時效熱處理t2分鐘後空冷，可以得到與Ti-6Al-4V相近的機械性質(YS: 871 MPa、UTS: 1042 MPa and EL: 14 %)。

Ti-7.5Mo alloy, developed from CMRT Lab, had been acquired the U.S. Patent (U.S. Patent No. 6409852) in 1999. It is a potential alloys for medical device. Ti-7.5Mo performed different thermomechanical treatment in this work to discuss effect on the mechanical properties, microstructure and precipitated phase.
Experimental results indicate that after hot rolling and then performing solution-treatment at T1℃ for t1, Ti-7.5Mo comprised primarily of a metastable α” phase also with a fine, acicular martensitic morphology. The bending modulus is 55GPa; the tensile modulus is 70GPa. It is similar to as-cast Ti-7.5Mo in microstructure, primarily phase and modulus.
In this work, Ti-7.5Mo after solution-treatment at T1℃ for t1 and then aging at T3℃ for t2 followed by air cooling has similar mechanical properties(YS: 871 MPa、UTS: 1042 MPa and EL: 14 %) to Ti-6Al-4V.
