High Milling Time Influence on the Phase Stability and Electrical Properties of FeMnSn Heusler Alloy Obtained by Mechanical Alloying.

FeMnSn Heusler alloy, obtained by mechanical alloying, was subjected to larger milling times in the range of 30-50 h to study the phase stability and morphology. X-ray diffraction studies have shown that the milled samples crystallise in a disordered A structure. The A structure was found to be stable in the milling range studied, contrary to the computation studies performed on this composition.
