Titanium aluminide (TiAl) alloys have higher specific strength and are desired for application to jet engine components. For this study, the machinability and effects for microstructure after cutting of cast and wrought TiAl alloy were investigated. Results show that any TiAl alloy can be machined with no cracks. Furthermore, microstructural bending was observed and controlled by the radial depth of cutting and the degree of tool wear. Finally, by adjusting the cutting conditions, the entire surface was cut from the rough forged state to the blade shape without microcracking.
