Abstract: In this study a Cu-Al-Ni alloy was manufactured by powder metallurgy (PM) method by mixing powder of 83%Cu-13%Al-4%Ni for 6 hrs. after that compacted at 650 mpa and sintered at 850 C for ( 3,4,5,6,7) hrs. and heat treated to investigate the influence of( hardness and shape recovery ) with multiple sintering time. To make sure that manufactured alloy are smart alloy XRD and SEM tests were done for 3 and 7 hrs . The result showed that Martensite layer was formed on surface. The result of hardness and recovery tests showed fluctuation of hardness and shape recovery with sintering time. The effect of sintering time on hardness is apposite on shape recovery. In this research artificial neural network was used to predict the behavior of alloy at sintering time between 3 and 7 hrs.
