The mechanical alloying process that included high-energy ball milling resulted in particle sizes of 25 mm and 80 mm on average for the Ni-Fe alloy that included 40 percent Ni. At room temperature, highenergy planetary ball milling was carried out over timespan ranging from 15 hours to 60 hours. All of the samples were sintered at the same conditions, which included a temperature of 650 degrees Celsius and a pressure of 30 megapascals. Because of factors such as a reduction in particle size(also known as a reduction in particle size), a low green body density of extended milling powders caused by agglomeration of powders (also known as agglomeration), and oxidation of powders while they are being milled, the porosity and densification of the samples increase as the milling hours accumulate. When increasing the milling speed, it is necessary to also increase the quantity of heat and pressure that is applied in order to achieve the desired density. The desired density of 85.4% was obtained after grinding the material for a total of sixteen hours.References
