Short-range order of liquid Ti 72.3 Fe 27.7 investigated by a combination of neutron scattering and X-ray diffraction

In this work we report on investigations into the topological and chemical short-range order of binary Ti 72.3 Fe 27.7 alloy melts. In order to analyse the structure, the melts were investigated by means of neutron scattering and energy dispersive diffraction of synchrotron radiation. The combination of both diffraction techniques allowed the determination of the partial Bhatia Thornton structure factors S NN ( Q ) and S CC ( Q ). The experimental results provide evidence of an icosahedral topological short-range order prevailing in the liquid that is accompanied by a pronounced chemical short-range order such that Ti –Fe nearest neighbours are preferentially formed.
