ARTICLE INFOShape memory alloys have the thermoelastic phase transformation, known as shape memory characteristics, which make them be used in wide technological applications compared to other alloys. Ni-Ti based SMAs compared to the other families have more applications especially in the biomedical field since they have high biocompatibility, high strain recovery, flexibility, and antirust. In this work, the studies conducted for NiTiCu SMAs were reviewed. Additionally, different manufacturing techniques used by researchers have been explained. Different characteristics of the alloys have been clarified and compared with some other families.

ARTICLE INFOShape memory alloys have the thermoelastic phase transformation, known as shape memory characteristics, which make them be used in wide technological applications compared to other alloys. Ni-Ti based SMAs compared to the other families have more applications especially in the biomedical field since they have high biocompatibility, high strain recovery, flexibility, and antirust. In this work, the studies conducted for NiTiCu SMAs were reviewed. Additionally, different manufacturing techniques used by researchers have been explained. Different characteristics of the alloys have been clarified and compared with some other families.

Despite of many interesting behaviors and attractive properties of Shape memory alloys (SMAs), there are some drawbacks and limitations that prevent them from being used in technology. But there are some treatment techniques that can be used to improve the behaviors of shape memory alloys. Also, they can remove or reduce the limitations of SMAs. In this study both and mechanical treatment techniques (Ball- and Roller-Burnishing Treatment, Surface mechanical attrition treatment, and Laser shock peening) and heat treatment techniques (Annealing, Normalizing, Hardening, and Tempering) have been clarified. And the effect of both treatment techniques of the properties of shape memory alloys have been reviewed.
