Non-linear elastic behavior of Ni-Fe-Ga(Co) shape memory alloy and Landau-energy landscape reconstruction
Original language description
We study the elastic behavior of single crystals of the Ni-Fe-Ga(Co) ferromagnetic shape memory alloy in a broad temperature range. Using tensile stress-strain measurements and ultrasonic characterization, we show that austenite and martensite phases of the given alloy exhibit strongly non-linear elastic responses, and we utilize the non-linear stress-strain data for constructing an energy function describing the observed behavior within the framework of the 4th-order Landau theory.
