Abstract

Systematic study on Ni-15% Fe-5% Mo by high energy ball milling of elemental Mo powder and pre-alloyed intermetallic FeNi₃ has been done to understand the formation kinetics during ball milling. X-ray powder diffraction (XRPD) has been employed to study the structure evolution. Mo atoms were found to dissolve into FeNi₃ within 40 h of milling. The speed of the diffusion of Mo atoms into FeNi₃ alloy was very slow as analyzed using the Johnson-Mehl-Avrami (JMA) equation. The substitution process destroyed the long-range FeNi₃ and NiMo bonds were formed. This change caused a decrease in magnetization.
