Abstract:

Heats of three depleted uranium alloys were melted to nominal compositions as follow a U-0.75Ti b U-0.75Mo-0.75Nb-0.75Zr-0.3V-0.5Ti c U-0.85Mo-0.85Nb-0.5Ti. The heats were vacuum-induction-melted in a zirconia-washed graphite crucible and bottom-poured into zirconia-washed graphite molds to produce 4.5-inch-diameter ingots weighing 220 pounds each. Chemical analyses from center, midradius, and surface locations at bottom and top of billets removed from these ingots are reported. Results of scanning for evidence of microsegregation coring with an electron probe are discussed. Author
