Ultrasonic-Assisted Shearing Characteristics of Fe-Based Amorphous Alloy Strips
Source abstract
Abstract
Ultrasonic-assisted scratching and bending tests were conducted on Fe-based amorphous alloy strips (Fe78Si9B13) to reveal (from a theoretical standpoint) the mechanism of ultrasonic vibration designed to improve the plasticity of amorphous strips during processing. The effects of different ultrasonic amplitudes on tool wear and each characteristic morphology of the strip section were investigated by conducting the ultrasonic-assisted shearing (UAS) experiments. The results indicate that the high-frequency stress field induced by ultrasonic vibration inhibits crack expansion by reducing the tensile stress σT within the strip, resulting in better machinability of the Fe-based amorphous alloy strips with low plasticity at room temperature. UAS replaces one-time-shear with multiple micro-shears, which can decrease the rate of tool wear during shearing of Fe-based amorphous alloy strips and improve strip section quality under appropriate amplitude conditions.
