Effect of tin addition on shape memory effect and mechanical properties of cu-al-ni shape memory alloy

Abstract EN

This study examines the effect of Sn additions on Cu-14% Al-4.5% Ni shape memory alloy.

Sn was added in three different percentages (0.3, 1, 3) % .

The alloys were mechanically tested both in compression test and micro hardness test.

Also, a thermo-mechanical test was performed on the alloys.

Results showed an increase in the transformation temperature outside the domain and also a better recovery strain with the increase of Sn percentage of 3% Sn addition showed the best results in mechanical properties while the 3% Sn showed a better Shape Memory Properties near to super This study examines the effect of Sn additions on Cu-14% Al-4.5% Ni shape memory alloy.
