The structure and properties of the vanadium chromium silicon alloys in the composition range V₃Si to Cr₃Si

Ten alloys have been investigated in the composition range from V₃Si to Cr₃Si across the ternary equilibrium diagram using X-ray diffraction, neutron diffraction, superconducting transition temperature and magnetic susceptibility measurements. Contrary to the results of previous workers it is shown that a two-phase region is present in the mid-composition ranges. The vanadium-rich (VCr)₃Si solid solution shows superconducting properties. A magnetic structure appears at low temperatures in certain alloys in the chromium-rich (CrV)₃Si solid solution range.
