“…In the last years, the use of SMAs in electric field is more and more increased, especially in piezoelectric and in self-healing devices. In the last decades, several investigations have been carried out in order to characterize such alloys and take advantage of their peculiar properties in different applications [3][4][5][6][7]. In particular, SMAs are able to recover the original shape, even after severe deformations.…”

ABSTRACT. Shape memory alloys (SMAs) are a wide class of materials characterized by the property to recover the initial shape. This property is due to ability of alloys to change the microstructure from a "parent" microstructure (usually called "Austenite") to a "product" microstructure (usually called "Martensite"). Considering the tensile resistance, SMAs stress strain curves are characterized by a sort of plateau were the transformations from Austenite to Martensite (in loading condition) and from Martensite to Austenite (in unloading condition) take place. In this work a simple model to predict the microstructure modification has been proposed and verified with an equiatomic NiTi alloy characterized by a pseudo-elastic behavior.KEYWORDS.
