Titanium aluminide turbine blade

Turbine blades
This turbine blade (shown on the left) is made from the intermetallic material titanium aluminide. It is built to withstand the intense heat and stresses generated inside a jet engine. Titanium aluminide’s low density means that a turbine blade made from it has about half the weight of a blade made from a traditional nickel alloy (shown on the right). The strength of the blade is a result of both the properties of titanium aluminide and the sophisticated techniques used to cast it.
