γ-TiAl合金的加工特性及能场辅助技术研究进展
Research Progresses for Machining Characteristics and Field-assisted Techniques of γ-TiAl Alloys
摘要
Abstract
γ-TiAl alloys,due to their low density,high specific strength and excellent high-tem-perature oxidation resistance had broad application potentials in the aerospace fields.However,due to their high brittleness and low room-temperature plasticity,they were considered typical difficult-to-machine materials,with challenges such as high cutting 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 ofγ-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 efficient machi-ning of γ-TiAl alloys.关键词
