Abstract

The present research is focused on the machinability of the gamma-TiAl alloys, also called in literature as titanium aluminides, under the milling process. In comparison with the alpha–beta alloys, the alloys solidified in the gamma phase present improved ratio between strength and density even at higher temperatures; however, hard and new machining problems appear. Currently, there is a lack of machining parameters for this kind of materials, and therefore, its inclusion in aeronautical and automotive applications is being delayed. This work summarizes the results of a testing program which offers an outlook on the cutting conditions when machining even more difficult-to-cut titanium alloys than the more spread and known structural alpha–beta alloys.
