Martensitic Transformation in Fe-Ni Alloys Nanostructured by Ball Milling

Abstract:

Fe86Ni14 powder was prepared by mechanical alloying of elemental powders in a highenergy planetary ball mill. X-ray diffraction was used to investigate structure and phase constitution of samples, and thermomagnetic measurements were used to study phase transformation temperatures. MA led to formation of bcc α-Fe and fcc γ-Fe based solid solutions. Significant reduction of martensitic points for MA alloys was observed that was attributed both to nanocrystalline structure formation and samples impurity at milling.
