Abstract

The effect of ageing on the microstructure and mechanical properties of five-layered tetragonal Ni₅₃Mn_23.5Ga_18.5Ti₅ alloy has been studied. The results show that ageing increases the amount and decreases the size of Ni₃Ti precipitates. In addition, the compressive strength of alloys is clearly enhanced and compressive strain is slightly decreased by ageing, which can be attributed to the strengthening of the Ni₃Ti precipitates and dislocation.
