The work here exposed, is framed in the line of development of slight materials with good properties, used to reduction of weight in different components for the aviation and automotion where very high temperatures are the main factor. In these fields, several components must withstand high temperatures maintaining a high resistance. The superalloys of type Gamma TiAl is a attractive alternative to other titanium and nickel-based alloys, due to high relationship resistance/weigh and the resistance to the corrosion. This work presents the results from turning tests on three types of Gamma TiAl alloys. Coating tools of integral hard metal are used, with different advances and cut speeds.
