Mixing instabilities during shearing of metals

The mechanisms behind deformation of multiphase solids are elusive. Here, the authors use X-rays and simulations to show that the same mechanisms causing rocks to fold occur at the micrometer scale in dual-metal lamellas of Ag/Cu and Al/Cu under high-pressure torsion, leading to vortices formation.
