Abstract

original image

The apparent switching temperatures (Tsw,app), which need to be exceeded by the environmental temperature (Tenv) to initialize a shape-memory effect (SME) in magnetosensitive dual- or triple-shape composites, are systematically adjusted by application of a constant weak alternating magnetic field. This adaptation of Tsw,app is fully reversible and results from the combination of environmental and inductive heating.
