Process for conditioning a component made of metal alloy with shape memory exhibiting two reversible shape memory states

摘要

The process for conditioning a component P made of metal alloy with double-effect shape memory according to the invention comprises the operations O1 to O7 consisting: - in forming O1 at ambient temperature T1 the component P in the shape constituting a first shape memory state, - in mechanically maintaining the component in its first shape memory state O2 and in mechanically heating the component maintained at the temperature T3 to bring it into an austenitic crystallographic phase state O3, - in abruptly lowering the mechanically maintained component to a temperature T4 O4 and in a stabilising heat treatment O5 while maintaining its austenitic state, and - in subjecting the component to a process of learning in order to form it in the second shape memory state O6, O7.
