  近年來鈦合金在生醫界的應用愈來愈廣泛也更加受注目而鈦合金有質輕、高比強度、優異的抗腐蝕性且良好的生物相容性,被視為很有潛力的生醫植入材。近年來更陸續有許多新型的鈦合金被開發出來。
  本研究中主要以Ti-Mo(II)合金為主要的研究材料並特別針對進行冷軋後熱處理的部份來研究其機械性質,並增列Ti-Mo(I)來對照。
在冷軋性質部份,經過不同冷軋壓延量的實驗結果可以比較出Ti-Mo(II)優於Ti-Mo(I),顯示出Ti-Mo(II)的冷加工性質良好。
  而在Ti-Mo(II)的熱處理方面,進行固溶處理的T9/tb與T9/ta所得的性質最好,只要固溶溫度選得準確(比ß相轉換溫度略高),而固溶時間縮短便可得良好性質的Ti-Mo(II)。
  而在熱處理方面的時效處理以T2/tf與T3/tf所得的性質最好,在時效方面應盡量避免低溫跟高溫時效,以免Ti-Mo(II)產生脆化。
  在拉伸測試實驗中,以固溶條件為T9/tb所得的整體性質最好,拉伸彈性模數也是最低的。
  In the recent years,the titanium alloys were studied. The alloys are light、hight strength、good anti-corrosiveness and nice biocompatibility.Titanium alloys are excellent implantal materials and new alloys are developed in the recent years.
  For the most part,my studies are about the Ti-Mo(II) alloy’s mechanical properties after cold rolled and heat treatment.
  In the part of cold rolled,Ti-Mo(II) is better than Ti-Mo(I).It indicates that the rolled ability of Ti-Mo(II) is good.
  In the part of heat treatment,Ti-Mo(II) with conditions of T9/tb and T9/ta are best.If you chose the correct solid treatment temperaturer and decrease the time of solid treatment.
  In the tensile test ,the whole properties of T9/tb condition are the best and the elastic modulus is also the lowest.
