SMART MATERIALS - PREDICTABLE TIME-BEHAVI OR OF CU-ZN-AL SHAPE-MEMORYALLOYS

The smart properties of some materials (magnetostriction, piezoelectri city, shape memory effect) relate their ability to react at environmen tal changes. Practical applications of the shape memory alloys need in dustrial tools for a plenty characterization of their capacity and a c omplete guarantee of their behavior. An experimental high resolution s tudy permits a predictive modeling and a path for standard industrial routines. A change in the room temperature, acting on parent phase, in duces a modification in the transformation temperature around 11 per c ent of this change.
