Abstract
Description
上記のように、本チタン合金は、一実施形態では、約0.1重量%〜約2重量%のケイ素(例えば、約0.5重量%〜約2重量%、例えば約0.5重量%〜約1重量%など)を含む。チタン合金中のSiの包含は、固溶強化及び/又はSi含有粒子の存在による強化のために、強度の増加及びHCF強度増加可能性をもたらす。さらに、Siは、チタン合金に微細化ミクロ組織をもたらすことができ、この微細化ミクロ組織は強度の増加及びHCF強度増加可能性をもたらし得る。処理の間に、合金中のSiレベルに応じて、溶体中のSiがケイ化チタン化合物として析出できる。ケイ化チタン化合物は、チタン及びケイ素の両方を含有する任意の化合物(例えば、Ti5Si3、Ti3Siなど)であってよく、他の元素(例えば、Sn及び/又はZr)を化合物中に含んでも、含まなくてもよい。
式中、Pz=ツェナードラッグ圧(Zener drag pressure)
C3=実質的に変動可能な幾何学的定数、最大5倍
γs=結晶粒界界面エネルギー
f=第2相粒子の体積分率
d=粒子の平均直径
第2相の粒子からのドラッグの影響を参照すると、1〜10%の体積分率及び1〜10ミクロンの平均直径が一般的である。結晶粒界が、C3の値当たりを動く第2相粒子とどのように相互作用して、その周りを取り巻くのかに対して、当分野において大きな意見の相違が存在する。
Cuが合金組成物中に成分として含まれる場合、Siが存在してもしなくても、Cuは、チタン合金中に比較的低温(例えば、合金中のCuレベルに応じて約800°F〜約1000°F又はそれ以上)においてチタン銅化合物の析出(例えば、Ti2Cu)を形成でき、これにより、α相は強化され、強度及びHCF特性の改善をもたらすことができる。Cuの添加は、一次及び二次α相の両方の精密化をもたらすことができ、これにより強度及びHCF特性の改善ももたされる。
上述のように、Snは場合により合金組成物に含まれてよく、Si含有合金においてケイ化チタン(例えば、Ti5Si3)相をよりも高温で安定化させるために潜在的に機能できる。したがって、Snは、処理の間、特に合金のβトランザス温度よりも高いが、ケイ化チタンソルバスのケイ化物ソルバス温度よりも低いβ処理温度におけるβ処理の間にビレット変換のためのより幅広いプロセスを可能にするために、βトランザス温度より十分高いケイ化物ソルバス温度を維持するように作用できる。
図1は、回転中心軸12を有する例示的ターボファンエンジンアセンブリ10の概略図である。例示的実施形態では、ターボファンエンジンアセンブリ10は、吸気側14及び排気側16を有する。ターボファンエンジンアセンブリ10は、高圧圧縮機20、燃焼器22及び高圧タービン24を備えたコアガスタービンエンジン18もさらに備えている。さらに、ターボファンエンジンアセンブリ10は、コアガスタービンエンジン18から軸方向下流に配置された低圧タービン26及びコアガスタービンエンジン18から軸方向上流に配置されたファンアセンブリ28を備える。ファンアセンブリ28は、ロータハブ32から半径方向外側に伸びるファンブレード30の配列を備える。さらに、ターボファンエンジンアセンブリ10は、ファンアセンブリ28と低圧タービン26との間に配置された第1のロータシャフト34及び高圧圧縮機20と高圧タービン24との間に配置された第2のロータシャフト36を、ファンアセンブリ28、高圧圧縮機20、高圧タービン24及び低圧タービン26が直列流体連通でターボファンエンジンアセンブリ10の回転中心軸12に関して共軸配列されるように備える。
