Abstract
Official abstract text for this publication.
A process for manufacturing a turbine engine component includes the steps of: providing a powder containing gamma titanium aluminide; and forming a turbine engine component from said powder using a direct metal laser sintering technique.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for manufacturing a turbine engine component comprising the steps of: providing a powder containing gamma titanium aluminide; and forming a turbine engine component from said powder using a direct metal laser sintering technique, wherein said powder providing step comprises providing a powder of an alloy having a composition consisting of 43.5 at % Al, 4.0 at % Nb, 1.0 at % Mo, 0.2 at % B, bal Ti. 2. The process of claim 1 , wherein said forming step comprises forming a turbine vane. 3. The process of claim 1 , wherein said forming step comprises spreading a layer of said gamma titanium aluminide powder on a platform and directing an energy beam onto selected areas of said gamma titanium aluminide powder to thereby melt the powder. 4. The process of claim 3 , wherein said forming step further comprises re-solidifying said gamma titanium aluminide by withdrawing said energy beam. 5. The process of claim 4 , wherein said forming process further comprises repeating said spreading, directing, and re-solidying steps to build up layers forming said turbine engine component.
