shape memory alloys (SMAs) exhibit an interesting research topic. The current limitation to the SMAs is that the cost of SMAs, made out of expensive elements such as Ni and Ti. In this work, the influence of different amounts of nickel (Ni), boron (B), and boron oxide (B6O) addition on the structure, mechanical, electrochemical, and tribological behavior of Cu - Zn - Al SMAs have been investigated. Cu–25Zn–4Al SMAs were produced by powder metallurgy technique with and without the addition of 0.5, 0.7, and 1 wt.% of Ni or B. After mixing the powders for 4hr, the alloys were prepared using 675MPa compact pressure. The alloys were subjected to a sintering process in a vacuum tube furnace with three steps. For microstructural and phases characterization of alloys with and without the addition of elements (Ni, B), optical microscopy (OM), scanning electron microscopy (SEM), and XRD diffraction analysis was carried out. The transformation temperatures of alloys with and without the addition of elements (Ni, B) were measured by differential scanning calorimetry (DSC). The shape memory properties of alloys with and without the addition of elements (Ni, B) were investigated using the shape memory effect test (SME). Electrochemical corrosion tests for alloys with and without the addition of elements (Ni, B) were carried out using the potentiodynamic polarization technique. XRD and microstructural analysis showed that all alloys compositions consisted of the predominating Cu5Zn8 phase. The results of transformation temperatures showed that the Ni and B additions have strong influences on the transformation temperatures of Cu – Zn – Al SMA. The results of electrochemical corrosion tests showed that an increase in Ni or B content up to 1wt. % improved the corrosion resistance of the unmodified Cu – Zn – Al SMA in 3.5 NaCl. In the second part, the influence of different amounts (1,3, and 5 wt. %) of boron oxide (B6O) additions on the mechanicals and tribology properties of Cu – Zn – Al SMAs with the addition of 1wt.% Ni or 1wt.% B has been investigated. Hardness measurement was used to assess the mechanical properties of 1, 3, and 5 wt.% B6O modified Cu – Zn – Al – Ni or Cu – Zn – Al– B alloy compositions. Wet sliding wear process was investigated for 1, 3, and 5 wt.% B6O modified Cu – Zn – Al – Ni or Cu – Zn – Al – B alloy compositions in distilled water at 2, 5, and 10 N normal loads at room temperature. The results of hardness measurements show that an increase in B6O content up to 3 wt.% improved the hardness of Cu – Zn – Al – Ni and Cu – Zn – Al – B SMAs. The tribological results show that the wear resistance of Cu – Zn – Al – Ni and Cu – Zn – Al – B SMA exhibited the best results with 3 wt. % of B6O addition. Further increase or decrease of B6O content decreases the wear resistance of the alloy
