Abstract
Although various achievements were made in past years to improve the mechanism of cystallization of metallic glass using annealing or deformation processes, the relationship between the micromechanisms of nanocrystalline formation in metallic glass while milling has not been thoroughly investigated. To elaborate on the connection between plastic deformation, stress, temperature, and nanocrystallization, the laminated Fe-based metallic glass foil (FMGF) was machined by side-milling with and without ultrasonic vibration. Plastic deformation can accelerate nucleation and therefore nanocrystallization with respect to phase separation in FMGF at high temperatures. The nanocrystal distributions in the FMGF milled with ultrasonic vibration is cyclical along the milling direction. The temperature of the nucleation and growth mechanism associated with phase separation is higher than that of the nucleation mechanism based on the linked-flus model. The results provide insights on the effects of plastic deformation and high temperature in the crystallization of FMGF.
