Description

The authors melted and cast an aluminum-uranium (Al-U) alloy by vacuum induction melting (VIM) prealloyed buttons made by arc melting. The resulting alloy casting displayed a large compositional gradient from top to bottom. The authors sampled the resulting casting for uranium to check homogeneity. The sampling revealed that the top of the casting contained 23.5 wt% uranium, and the bottom (an average of two samples) contained 42.4 wt% uranium. Although each button contained 36.5% uranium, these analyses show that the solidified casting was inhomogeneous. If the buttons were homogeneous, the segregation occurred during induction melting, and this method may not ... continued below

Although each button contained 36.5% uranium, these analyses show that the solidified casting was inhomogeneous. If the buttons were homogeneous, the segregation occurred during induction melting, and this method may not be feasible for making AL-U alloys. If the buttons were not homogeneous, perhaps arc melting the buttons more times would have helped. Bottom pouring the Al-U melt into a mold for faster cooling could also help prevent segregation.
