Shape memory alloy action lock with a structure that can hold securely locked. It is related to the mechanism. 10 State of the art: Shape memory alloys (SMAs) retain their original shape after a specific temperature change. These are special metal alloys that can return to their original shapes. These alloys are thermomechanical. Thanks to its properties, it is widely used in various industries. Shape memory alloys, especially shape memory arising from phase transformation and 15 It is notable for its superelastic behavior. Shape memory alloys were first discovered in the 1960s and are primarily nickel-titanium. It is composed of (NiTi) alloys. In later years, copper, aluminum, iron and New alloys have been developed by mixing different elements such as gold. These alloys... the development of properties such as mechanical strength, temperature resistance and biocompatibility 20 This allows for the improvement of shape memory alloys. Today, development through innovations in nano-engineering techniques and materials science It is supported. Shape memory alloys (SMAs) are highly malleable, capable of undergoing pseudoplastic deformation. After experiencing pseudo-deformations due to not being exposed to high voltages, 25 These are materials that can return to their original state when the temperature increases. The material has this false characteristic. Significant forces during recovery following plastic deformation. It is able to implement. 2 Another important application area for shape memory alloys is in security and locking. They are systems. Shape memory alloys are resistant to temperature, electric current, or mechanical force. smart lock mechanisms can be activated thanks to these features.
