Abstract
The microstructural changes of Al-22 wt%U and Al-46 wt%U alloys containing 3 wt% Zr were investigated after heat treatment at 620°C for 1 to 45 days. Though it is reported that addition of ~3 wt% Zr stabilizes the (U,Zr)Al3 phase at room temperature, the present investigation shows that the (U,Zr)Al3 phase is not stable but slowly transforms to the U0.9Al4 phase. The high temperature creep curves generated for these ternary alloys showed a wavy pattern which also suggests that the (U,Zr)Al3 phase is not stable.
