The Crystal Structures of Ti2Cu, Ti2Ni, Ti4Ni2O, and Ti4Cu2O

Abstract

The crystal structures of Ti2Cu, Ti2Ni, Ti4Ni2O, and Ti4Cu2O were determined using powder specimens examined by x-ray and neutron diffraction. Lattice constants were determined for all four phases using x-ray powder diffraction films. Atom positional parameters of all four phases were determined from observed neutron intensities. X-ray diffraction calculated intensity data were presented also for the phase Ti/sub 2/Cu to point out the particular suitability of neutron diffraction in this case. Interatomic distances were determined using the positional parameters obtained from neutron diffraction.
