New orthorhombic phase in U-Fe-Al-Si system Academic Article uri icon


  • Abstract A new quaternary phase with the approximate composition U–18.6 at% Fe–29.2 at% Al–32.6 at% Si was observed in U–Fe–Al–Si system. The crystal structure of this phase was investigated by electron diffraction and X-ray powder diffraction techniques. It has an orthorhombic unit cell with lattice parameters a= 12.241 Å, b= 18.362 Å and c= 4.066 Å and can be described by the Immm space group.
