Thermodynamics of Shape memory Behaviours
Abstract :
Smart materials play important roles in today’s technology. Shape memory alloys are metallic class of smart materials and they have promising potentials in applications that require high strength and functionality. The origin of the unusual properties of shape memory alloys is thermo-elastic martensitic phase transformation. In this study, thermodynamic theories used in analyzing the thermo-elastic martensitic phase transformations are reviewed by considering equilibrium thermodynamic theory and phonemenological thermodynamic theory. Then, transformation temperatures and heats are expressed by thermodynamic equations. Finally, shape memory behaviors are investigated by generalized thermodynamic theories.
