PHASE TRANSFORMATION STUDIES ON Fe-Co-Sn ALLOYS.

Abstract

Phase transformations in (FeCo)//7//5Sn//2//5 alloys have been studied by X-ray diffraction, scanning electron microscopy and hardness measurements. The phases in the quenched alloys are alpha -Fe(Sn), Fe//1//. //3 Sn, Fe//3Sn//2, Co//3Sn//2 and alpha -Co(Sn). The lattice constants have been determined. Preliminary diffraction studies have indicated the necessity of reinvestigation of high temperature phase equilibria.
