WebThe ability of some alloys to remember their shape at two different temperatures is called shape memory effect (SME), and the respective materials are referred to as shape memory alloys (SMAs). SME is governed by a non-diffusive first-order phase transformation called martensitic transformation (MT). WebThe search for a substitute alloy is primarily motivated by the goal of reducing costs. Cu-based alloys have received significant attention because copper is cheaper than Ni and Ti. Furthermore, Cu-based alloys offer ease of fabrication, as well as competitive strain recovery and damping properties with respect to NiTi SMAs.
WebOverview. The two most prevalent shape-memory alloys are copper-aluminium-nickel and nickel-titanium (), but SMAs can also be created by alloying zinc, copper, gold and iron.Although iron-based and copper-based SMAs, such as Fe-Mn-Si, Cu-Zn-Al and Cu-Al-Ni, are commercially available and cheaper than NiTi, NiTi-based SMAs are preferable … WebJul 1, 2024 · Cu-based shape memory alloys have been hyped as the ‘heir’ and pragmatic substitute to NiTi alloys for shape memory applications.
