Microstructure and Shape Memory Effect of Cu-Al-Be-Mn Quaternary Shape Memory Alloys

Abstract:

Copper based shape memory alloys are the alloys prepared with the combination of 66-88 wt% of copper, 10-14 wt% of aluminum, 0.3-0.6 wt% of beryllium and 0.1-0.4 wt% of manganese in the induction furnace through ingot metallurgy. The prepared SMAs is subjected to homogenization, it was observed that the samples exhibits Beta phase at high temperature and shape memory effect after going through step quenching to a low temperature. Microstructure and Shape memory effect was studied with the help of optical microscope and bend test respectively. It was seen that with increase in wt % of manganese the shape memory effect also increases.
