Özet

—Herein, we investigated Al–[9 – x] at % Ni–x at % Co (x = 2 and 5) ternary alloy, which has a wide range of applications in terms of tribological properties and magnetic properties. The impact of grain size on the electrical, thermal, magnetic and mechanical properties of these alloys was investigated. Results demonstrated that a decrease in the average grain size of these alloys increases their electrical resistance and decreases their thermal conductivity. Moreover, mechanical properties such as strength, durability and hardness improved depending on grain size. The alloy composition that exhibits optimum properties is the Al– 4 at % Ni–5 at % Co alloy. The magnetic properties, such as magnetic transition temperature and magnetisation curves were determined for both alloy compositions.
