Using a high temperature torsion test apparatus, the shape recovery property of three mica glass ceramics are clarified. The shape memory phenomenon occurs in the mica glass ceramics called 'MACERITE' or 'PHOTOVEEL' which are different from 'MACOR' in chemical composition of the glass matrix. The pre-deformation temperature range and shape recovery temperature range in which the shape recovery property is best changes with chemical composition of the glass matrix. The stress relaxation temperature range corresponds to the shape recovery temperature range. The thermal expansion curves show that there is a break point which suggests the glass transition point.
