“…The ultimate tensile strength of more than 1% nickel-containing alloy is around 160 MPa. Compared to previous work in Refs [32], UTS of Mg-3%Ni alloy is 124.4 MPa and elongation is 1.16%, significant improvement is observed here. The grain size of Mg-1.4Ni alloy is smaller and more refined compared to Mg-0.7Ni alloy.…”

Previous research on Mg-Ni alloys focused on the mechanical characteristics and damping behaviour in the presence of Zn and rare earth elements. There has not been much research on the Mg-Ni-Mn alloy’s microstructure, mechanical properties, and corrosion behaviour. The present research work fulfils this gap by concentrating on the microstructure, mechanical and corrosion characteristics of Mg-Ni-Mn alloys. Here, different Mg-Ni-Mn alloys were developed by varying the nickel and manganese content. The microstructure of the developed alloys was studied using optical microscope and scanning electron microscope. Ultimate tensile strength and micro hardness of all alloys were performed on tensometer (room temperature), and Vickers hardness tester respectively. The corrosion rate of Mg-Ni and Mg-Ni-Mn alloys was measured at 3.5 wt. % NaCl solution by immersion test. The result shows that the nickel and manganese presence refine the grain size of magnesium. XRD analysis confirmed the presence of α-Mg and Mg2Ni phases in Mg-Ni alloys. Along with these phases, the Mn phase was observed in Mg-Ni-Mn alloys. Mechanical properties such as ultimate tensile strength and hardness of pure magnesium were increased in the presence of Ni and Mn. However, the presence of manganese in Mg-Ni alloy shows an adverse effect on corrosion behaviour. The corrosion rate of the Mg-Ni alloy was accelerated in the presence of manganese.

“…The bright precipitate at the grain boundaries (marked B, G) of the alloy is rich in Ni. EDS, XRD, and available literature identify this phase as Mg 2 Ni[29]. In the microstructure, many isolated particles are observed.…”

“…The increase of copper content, within the limit ranges, has been proven to enhance the antimicrobial activity [ 12 , 13 ]. However, the addition of copper in selective metallic materials might hamper the corrosion resistance and mechanical properties, leading to the non-desirable performance for practical applications [ 14 , 15 ]. Liu et al illustrated that at least 5% (w/w) of Cu in Ti-Cu alloys was required to obtain a stable antibacterial efficiency [ 12 ], but only a 75% reduction of bacterial cell numbers was achieved for Ti-10 Cu alloy (containing 10% Cu) against anaerobic Porphyromonas gingivalis over 24 h of incubation [ 16 ].…”
