Effect of Ni on Microstructure of Fe65B15Si10Ti5Al5 Fe-Based Prepared by Mechanical Alloying

In this study, iron-based alloy with Fe65B15Si10Ti5Al5 was prepared by mechanical alloying method . The effect of nickel content on its microstructure with 200 hours of milling was investigated. In this study X-ray diffraction and scanning electron microscopy equipped with chemical composition analyzer. Addition of nickel in the Fe65Ti5Al5B15Si10 alloy system and its increase reduced the intensity of all peaks, their broading and also the shift of peaks to lower angles. This indicates a decrease in the size of iron-alpha phase crystals and an increase in lattice strain due to an increase in nicke elmentl. Also, an increase in nickel reduced the particle size due to milling at the same hours of alloying.
