Abstract
AFTER high temperature plastic deformation and cooling under load to room temperature, glass-ceramics containing mica as the principal crystalline phase retain a near-perfect memory of their undeformed state, the plastic strain being recoverable by a subsequent high temperature anneal. Activation energy measurements support the hypothesis that dislocations in the mica crystals control the shape-memory process.
