chamber and the irradiation stage are shown in Figure 1. Disc samples of three DU alloys
were irradiated to doses of 0.1, 1.0, and 3.0 dpa. Microstructural analysis for both the
unirradiated and the irradiated DU alloys will be performed using transmission electron
microscopy (TEM). The results of TEM analysis are not available for this paper.

3. Results and Discussion
Secondary electron images of the Sample A microstructure are presented in Figure 2.
Two phases comprise the alloy microstructure: a U(Al,Si)3 phase and an Al phase. The
U(Al,Si)3 phase has an approximate composition in at% of: U27-Alo-Sin ( 1 at%).
Figure 2. Secondary electron images at low (left) and high (right) magnification
of the microstructure observed for alloy A. The black phase is Al, and the bright
contrast phase is a U(Si,Al)3 phase.
