A shape memory device, and thus the alloy, when not operating is generally held in the martensitic condition. Also the shape memory effect depends on the retransformation of the martensite to the parent phase (i). Use of an alloy in a temperature controlling device, therefore, demands reliability and reproducibility of this retransformation temperature with shape memory cycles and more particul...

Shape Memory Alloys (SMA) is a material that can return to its original shape after undergoing mechanical deformation. The most commonly SMA used the Ni-Ti alloy. However, it high cost. So necessary have alternative materials, for instance Cu-Zn-Al. Several studies related Cu-Zn-Al poor properties. there further research required in order determine heat treatment process of Alloys. In this stud...

Shape memory alloys have again appealed a lot in recent years as new special materials of unusual macroscopic features that make them interesting for study and research as well as for their multifunctional application in various branches of techniques. Shape memory refers to the ability of certain plastic metals and alloys to regain their original shape during the heating process due to complet...
