Abstract

A preliminary phase-equilibria study has been made of the manganese-indium alloy system by means of thermal analysis (cooling curves) and metallographic studies (photomicrographs). Ferromagnetism has been found to exist in alloys containing up to 70 atom percent manganese and has tentatively been attributed to the compound Mn₂In. A phase diagram has been proposed, on the basis of the data obtained, in which the indium rich portion of the system consists of indium plus Mn₂In, while the manganese rich portion is made up of a manganese solid solution. Additional experiments have been outlined to further identify the nature and extent of the phases present. A new scheme of chemical analysis has been applied to the alloys with good success.
