Identification of the structure of a new Al-U-Fe phase by electron microdiffraction technique Academic Article uri icon

abstract

  • Abstract The particles of an unknown intermetallic phase with the approximate composition Al 10 Fe 2 U 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 A; its crystal symmetry can be described by the Cmcm space group.
