Abstract

Slip and twinning are the two fundamental modes by which metals and alloys can deform plastical1y. Slip occurs when crystal planes glide past each other. This is achieved by the passage of dislocations on different glide planes. Since the Burgers vector of the glide dislocations is always a lattice vector, the atoms during the slip motion move from one lattice site to the adjacent equivalent one. Consequently, the slipped and unslipped regions have identical orientation.
