ABSTRACT Ultrasonic vibration (UV) assisted micro-bending experiments were conducted on TA1 titanium alloy sheets   to study its effectiveness in controlling springback under size-reduced conditions. The influences of ultrasonic amplitude and holding time on bending force and springback behavior were systematically evaluated.

Introduction Tumor metastasis is a multi-stage process in which invasion constitutes the critical gateway. Tumor invasion proceeds via two distinct modes: individual movement and collective migration. Individual movement, such as amoeboid or single-cell invasion, is driven by epithelial–mesenchymal transition, enabling tumor cells to detach from the primary tumor and infiltrate adjacent stroma.
