deformation twinning

Deformation twinning is a process in materials, especially metals and crystals, where the structure of the material undergoes a sudden change under stress. Instead of simply bending or breaking, the atomic arrangement inside the crystal shifts in a specific, symmetrical manner, creating a mirror-image region known as a twin. This effectively helps the material accommodate deformation, enhancing toughness and strength. Deformation twinning is essential in explaining how some materials can withstand significant forces without failing, contributing to their overall mechanical properties.
