OSTI ID:4147061
Phase relationships in the bimary systems Y-Fe, Y-Ni, and V-Cu are being studied. Yttrium, provided by GEANPD, and high purity alloying metals are being employed for all alloys. Twenty-five 20-gram "button" ingots were arc melted in each system. Conventional nonconsumable electrode arc melting techniques are being employed. Compositions were chosen at appropniate intervals from 0 to 100% of the alloying addition. Portions of each ingot in the Y-Fe and Y-Ni systems were submitted for metallographic sthdy. A cursory melting-point study was con ducted for selected alloys in both binary systems. Work with the Y-Cu alloys is being delayed until it becomes clear how much effort must be expended in esthblishing the phase boundaries in the other two diagrams. (auth)
