EFFECTS OF CARBON ON THE CONTROL AND DISTRIBUTION OF TITANIUM IN URANIUM - 0.8 w/o Ti CASTINGS

摘要

A series of small-scale U-0.8 w/o Ti alloy castings (~4" OD × 10" long) were made under conditions designed to produce ingots of varying carbon content. These ingots were destructively sampled to expose the longitudinal center line of each casting for a metallographic analysis and transversely sampled to give an edge-center, top-bottom, alloy-carbon distribution pattern.nThe results show that low carbon (<100 ppm) must be maintained to achieve predictable recovery and uniform distribution of titanium (target +0.1 w/o).
