Investigation into the material removal mechanism and surface integrity of Zr-based bulk metallic glass via rotary ultrasonic vibration grinding

This study demonstrates that rotary ultrasonic vibration-assisted grinding (RUVAG) significantly improves the surface integrity and reduces material removal defects of Zr-based bulk metallic glasses compared to conventional grinding by introducing intermittent contact that mitigates stress concentration and lowers surface roughness by approximately 21%.
