Abstract
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.
期刊介绍：
The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
