Microstructure evolution mechanism of tungsten induced by ultrasonic elliptical vibration cutting at atomic/nano scale

•Dislocation, amorphous and nanocrystal are the mechanisms of plastic deformation of tungsten.•Tungsten surface forms nanocrystals under UEVC compared with common cutting.•The instantaneous shear stress of UEVC is three times that of common cutting.•The relationship between shear stress and microstr...
