Abstract
Usage of shape memory alloys (SMAs) in mechanical work applications is influenced by electrical control system and parameters, material properties and environment factors. Determining the thermal behavior of a nitinol material (Nickel-Titan alloy) with a scanning differential calorimeter (DSC) and analyzing the mechanical and electrical responses on a testing laboratory equipment can be observe the spring behavior on different numbers of cycles. The control of material actuation is made through electrical parameters variation with nice results in different work regimes.
