This research aims to reduce the number of experiments by using the Taguchi technique. It will be applied on adding copper nano particles and study it's effect on shape recovery for a shape memory alloy (83% Cu- 13% Al- 4%Ni). Different proportions of nano were added to the alloy in return for changing the proportion of copper while maintaining the proportions of nickel and aluminum constant. Powder metallurgy technique was used to manufactured the samples. Two types of tests were performed: physical tests, including X-ray diffraction (XRD) and scanning electron microscopy (SEM), were used to inspect raw materials before manufacturing and to inspect samples after manufacturing. A mechanical test of the shape memory effect (SME%) was conducted for different a compression ratio. The results indicate that the addition of copper nano particles reduces shape recovery at a compression ratio of 3%. Analysis of results represented by Signal to Noise ratio (S/N) and ANOVA show the most significant factor in shape recovery was copper nano particles followed by copper particles and the most contribution factor was copper nano particles in percentage 87.82%.
