激光辅助切削Inconel 718合金的分子动力学模拟
Laser-assisted machining of Inconel 718:a molecular dynamics simulation
摘要
Abstract
This study investigates the laser-assisted machining(LAM)process of Inconel 718 alloy using molec-ular dynamics simulations,with a focus on the influence of laser power on cutting behavior.The results indicate that the thermal softening effect induced by LAM significantly enhances the material's plasticity and reduces cut-ting forces,thereby reducing the input of mechanical work.With increasing laser power,the thermal softening effect further intensifies,and the atomic stacking phenomenon on the workpiece surface is alleviated.Moreover,LAM mitigates the phase transition during machining,suppresses the formation of dislocations,and reduces the formation of stacking faults,resulting in a more stable internal structure of the machined workpiece.关键词
