Abstract

The particles of an unknown intermetallic phase with the approximate composition Al10Fe2U were observed in a ternary Al-Fe-U alloy. The structure of this phase was investigated in a transmission electron microscope using a microdiffraction technique based on analysis of the symmetry and relative positions of reflections in the zero-order and high-order Laue zones. The phase has an orthorhombic C-centered unit cell with lattice parameters a=8.900, b=10.190 and c=8.993 Å; its crystal symmetry can be described by the Cmcm space group.
