Abstract (EN): Intermetallic titanium aluminide alloys are used in the high technology engineering field with the goal of achieving weight reduction in different components, exposed to corrosive environments and high temperatures in aeronautical and automotive industries. Despite their attractive properties such as low density, high strength, high stiffness and good corrosion, creep and oxidation resistance, the machinability of titanium aluminide alloys is difficult due to its high hardness, chemical reactivity, and low ductility. This article reviews the state of the art regarding the machinability of titanium aluminide alloys and focuses on the analysis of the milling process, namely the process parameters, surface integrity and cutting tools. The influence of titanium aluminides properties on the machinability is also discussed presenting some current trends and further needed research.
