The method of conditioning an article of shape memory metallic alloy having a double-action shape memory in accordance with the invention comprises the operations of forming at ambient temperature the article to the shape constituting a first shape memory state, mechanically maintaining the article in its first shape memory state and heating the mechanically held article to a temperature to transform it into a state of the austenitic crystallographic phase, suddenly lowering the mechanically held article to a selected temperature and subjecting it to thermal stabilization treatment while still preserving its austenitic state, and subjecting the article to an education process in order to shape it into the second shape memory state.
