Slip bands in metals

Slip bands in metals refer to the visible lines or features that appear on the surface of a metal sample when it undergoes plastic deformation, primarily due to slip, which is the primary mechanism of deformation in crystalline materials. Here’s a deeper explanation: ### Mechanism of Slip 1. **Crystal Structure:** Metals have a crystalline structure, meaning they consist of atoms arranged in a specific, repetitive pattern. The arrangement allows for deformation to occur along certain directions, known as slip planes.
