摘要: 采用粉末注射成形方法制備了鈦合金坯體,利用溶劑脫脂和熱脫脂方法脫除坯體中粘結劑,并在真空氣氛下燒結致密鈦合金樣品.真空燒結后,經960℃和140MPa熱等靜壓處理,在720~760℃進行1~1.5h退火處理獲得的樣品微觀結構為均勻的雙態組織,由許多等軸較小的α晶粒和少量尺寸較小的β晶粒組成.XRD分析結果表明,當退火溫度高于800℃時,樣品存在Ti₃Al雜質相.

Abstract: Titanium alloy parts were prepared by metal injection molding, binder was removed from the parts by solvent debinding process, and the brown parts were densified in vacuum atmosphere. The as-sintered specimens were treated through hot-isostatic pressure at 960℃ and 140 MPa, and titanium alloy compacts were annealed at 720-760℃ for 1-1.5 h. SEM observations showed that the titanium alloy had a uniform dial microstructure with many equiaxed a grains and a little β grains. XRD results indicated that Ti₃Al phase was found in the alloy when the annealing temperature was higher than 800℃.
