Abstract: γ-TiAl alloys,due to their low density, high specific strength and excellnt high-temperature oxidation resistance had broad application potentials in the aerospace fields. However,due to their high britleness and low room-temperature plasticity,they were considered typical difficult-tomachine materials,with challenges such as high cuting forces, rapid tool wear and surface defects during the machining processes. In recent years, field-assisted machining technologies provided new solutions to these issues. The material properties, machining characteristics,and surface integrity of γ -TiAl alloys were systematically analyzed, with a focus on the research progresses of field-assisted machining technologies,including their applications in reducing cutting forces, extending tool life and improving surface quality. Additionally, the current research limitations and future development trends were sorted out,aiming to provide theoretical and technical references for the eficient machining of γ TiAl alloys.
