Variation in Transformation Temperature and Shape Memory Effect in Cu-Al-Be Shape Memory Alloys with the Effect of Quaternary Elements

Abstract:

Cu-Al-Be Ternary alloys are prepared by ingot metallurgy route, which exhibits parent phase or Austenite phase at high temperature and Martensite phase at low temperature and also exhibits shape memory effect upon quenching to lower temperature. The Cu-Al-Be SMA was in the range of 10-12wt% of Al and 0.4-0.5 wt% of Be is chosen for present study and different amount of quaternary element is added to the ternary alloy. The variation in shape memory effect, transformation temperature and microstructure is studied by using bend test, differential scanning calorimeter and Optical microscope.
