1. A shape memory material formed from a previously formed shape memory material having a first transformation temperature, the shape memory material comprising at least two transformation temperatures wherein a second transformation temperature is imparted to a predetermined portion of the shape memory material following formation of the previously formed shape memory material;
wherein the second transformation temperature is imparted by a method including applying energy to the predetermined portion of the shaped memory material such that the predetermined portion is approximately fully melted and produces a change in the local chemical composition to provide additional transformation temperatures;
wherein the second transformation temperature is not a temperature associated with a rhombohedral phase.
