Abstract
Several methods have been proposed for interpolation of the value of physical parameters of quaternary alloys from those of their constituent sub-alloys. These expressions agree when non-linear bowing terms are not required; they differ in how the bowing terms of the bounding ternaries should be utilized. Common interpolation expressions for quaternaries can be generalized into two groups: 1) those that use a linear interpolation of the nearest ternary parameter values and 2) those that interpolate over binary values with a bowing term derived from the bounding ternaries. The second group of methods is equivalent to a polynomial expansion over the alloy's interpolation space. A general polynomial expansion of the value of an alloy parameter is described for alloys with arbitrary numbers of elements, including quinary and senary alloys.
