Shape memory alloys are a modern class of materials presenting the capacity to recover the initial shape even after high deformation values. This is due to the ability to change the microstructure under the effect of an external mechanical action at relatively low temperatures, that do not allow the recrystallization of the grains. These transformations are reversible, so to recover the initial structure is possible. The results were compared with the theoretical calculation of the phases quantities obtained from the application of a new analytical model capable of predicting the actual phases content in a shape memory alloy or from the super elastic behaviour.

Abstract

Shape memory alloys are a modern class of materials presenting the capacity to recover the initial shape even after high deformation values. This is due to the ability to change the microstructure under the effect of an external mechanical action at relatively low temperatures, that do not allow the recrystallization of the grains. These transformations are reversible, so to recover the initial structure is possible. The results were compared with the theoretical calculation of the phases quantities obtained from the application of a new analytical model capable of predicting the actual phases content in a shape memory alloy or from the super elastic behaviour.
