Investigation on Relationship between Shape Memory Effect and Interconnection Porosity under Multiple Sintering Time of Smart Alloy Cu-Al-Ni

Abstract

For Producing shape memory alloy In this study the powder metallurgy method has been used to manufacture Cu-13%Al-4%Ni alloy by producing 5 samples every sample sintered in difference sintering time( 3,4,5,6,7) hours. The samples also heat treated to stabilize Martensite phase. The result of shape recovery and porosity testing analyses by using artificial neural network predicting system to predict shape recovery and porosity behavior between three and seven sintering hours with smaller time step Due to there is no physical relationship between porosity and shape recovery,. The relationship between porosity and shape effect curved by using excel program taking the result from predicting system of artificial neural network. The curves shows direct relationship between shape recovery and porosity with respect to time.
