Grinding of Gamma TiAl Intermetallic Alloys

Titanium intermetallic materials are likely to play a significant role in the production of future aeroengines. Although applicable for only a relatively narrow range of applications, gamma-TiAl intermetallic materials are nonetheless the focus of all leading aerospace/gas turbine manufacturers, as a replacement for some nickel-based superalloy components in parts of the engine subject to temperatures < 900 °C. This work presents the results from grinding tests on two types of Gamma TiAl alloys.
