Shape memory effects coupled with superelasticity are the distinctive characteristics of shape memory alloys (SMAs), a type of metal. When these alloys are subject to thermomechanical processing, they have the inherent ability to react to stimuli, such as heat. As a result, these alloys have established their usefulness in a variety of fields and have in recent years been chosen for use in stents, sensors, actuators, and several other forms of life-saving medical equipment. When it comes to the shape memory materials, nickel–titanium (Ni-Ti) alloys are in the forefront and have been chosen for use in a spectrum of demanding applications. As shape memory alloys (SMAs) are chosen for use in critical environments, such as blood streams (arteries and veins), orthodontic applications, orthopedic implants, and high temperature surroundings, such as actuators in aircraft engines, the phenomenon of environment-induced degradation is of both interest and concern. Hence, the environment-induced degradation behavior of the shape memory alloys (SMAs) needs to be studied to find viable ways to improve their resistance to an aggressive environment. The degradation that occurs upon exposure to an aggressive environment is often referred to as corrosion. Environment-induced degradation, or corrosion, being an unavoidable factor, certain techniques can be used for the purpose of enhancing the degradation resistance of shape memory alloys (SMAs). In this paper, we present and discuss the specific role of microstructure and contribution of environment to the degradation behavior of shape memory alloys (SMAs) while concurrently providing methods to resist both the development and growth of the degradation caused by the environment.

“…In realistic applications, as the alloy is exposure to corrosion solution for a period of time they are exhibit to corrosion and pitting, for that reason study of corrosion behavior like corrosion current and potential and pitting potential of the alloys are require to be done before they are put into biomedical and industrial applications. Since SMAs find a wide application in the marine, aerospace applications and it is also used in the surgical medical use such as guide wire, so it becomes necessary that the shape memory alloys high corrosion resistance to the environment in which it is being used, aim of this search it is important to evaluate the corrosion current, corrosion potential and pitting potential of the SMAs that used in biomedical applications [1].…”

The corrosion behavior of martensite phase in Cu-Al-Be shape memory alloy with aging at 150℃ at time 2,4and 6 hour and quenching ice water with salt, water at room temperature and oil media study by open circuit potential, tafal polarization and cyclic polarization. The microstructure of martensite study by optical microscope and x-ray diffraction(XRD) and transformation temperature was determined by Differential Scanning Calorimeter (DSC).the result show aging martensite at 150℃ at 2 and 4 hour have high open circuit potential, low corrosion current density , high corrosion potential and pitting potential than martensite without aging.
