幾つかのTi−6Al−4Vプリフォームをアディティブ・マニュファクチャリングによって製造した。具体的には円筒形のTi−6Al−4VプリフォームをEOS GmbH(Robert−Stirling−Ring 1、82152 Krailling/ミュンヘン、ドイツ)から入手可能なEOSINT M 280直接金属レーザ焼結(DMLS)アディティブ・マニュファクチャリングシステムによって製造した。チタンについての製造業者の標準推奨操作条件に従ってTi−6Al−4Vプリフォームを製造した。その後、プリフォームを約958℃(1756°F)または約972℃(1782°F)の素材温度に加熱した。次に、様々な量の真歪下、約390℃〜400℃(734°F〜752°F)の金型温度を用いて、それらの円筒形プリフォームの一部を鍛造して、円筒形最終鍛造製品を製造した。円筒形プリフォームに、円筒の軸に対して平行方向に真歪をかけた。残りのプリフォームは、未鍛造のままにした。その後、最終鍛造製品の一部を約732℃(1350°F)の温度でおおよそ2時間焼鈍して、焼鈍された最終鍛造製品を製造した。その後、引張降伏強度(TYS)、極限引張強度(UTS)および伸度(すべて方向でのもの)を含む、未鍛造プリフォーム、最終鍛造製品および焼鈍最終鍛造製品の機械的特性を、試験した。結果を図3〜4に示す。歪レベルごとに数個の試料を試験し、結果を平均した。TYS、UTSおよび伸度を含む機械的特性をASTM E8に従って試験した。
