RESEARCH ON THE FREEZING AND MELTING POINTS OF IRON ALLOYS

Abstract

Progress is reported on the development of phase diagrams for Fe-C-Ni, Fe-Ir, and Fe-Os alloys. Effort is being directed toward refinement of electron-probe microanalysis techniques for the determination of Ni in quenched phases of Fe-CNi alloys. The thermal analysis of the Fe-rich portion of the Fe-Ir system is complete; the peritectic transformation occurs at 1538 C. Seven alloys were prepared in the Fe-Os system. The Fe-rich end of the phase diagram is similar to that of Fe-Ir. The peritectic transformation takes place at 1550 C.
