The effects of milling time and heat treatment on the micro-structural and magnetic behavior of Fe42Ni28Zr8Ta2B10C10 synthesized by mechanical alloying

► Amorphous phase content was about 92% at 176 h of milling. ► Coercivity reduced to about 23 Oe at 176 h of milling. ► At 198 h of milling magnetization increased rapidly due to recrystallization. ► Heat treatment reduced the coercivity to about half. ► The obtained coercivity was the lowest among similar alloys.
