Abstract

TiNi alloys are used in places where requiring precision jobs for the last few decades. Thermally induced shape memory alloys such as TiNi, exposures in use and the temperature causes the aging effects on alloy. In our experimental study, we have aimed to investigate of aging effects depends on time and temperatures for TiNi alloys. Three different temperature values and seven waiting periods applied and totally 22 experiments were conducted and the results were examined. Time depended results, especially for 200 °C samples exhibited more stable state than 300 and 400 °C. When the temperature values are considered, remarkably increase is observed after 200 °C.
