Abstract

The lifecyle environmental impact was compared between two gamma titanium aluminide (gamma-TiAl) alloys, Ti-46Al-8Nb and Ti-46Al-8Ta (at.%), and a standard nickel superalloy (INC713LC) as used for investment cast components in the low pressure (LP) turbine section of aircraft engines. The results su...
