Abstract
A blade used in a gas turbine engine in which the blade is formed of a blade portion made from a metallic material, and a tip portion made of a ceramic material, the tip portion forming at least 10% of the overall blade length such that the blade is lighter than a all-metallic blade. The ceramic tip of the blade allows the blade to withstand higher temperature environments without damaging the blade as would occur in an all-metallic blade.
