Deviation from vegard’s law
WebAug 3, 2010 · Vegard's law states that, at a constant temperature, the volume of an alloy can be determined from a linear interpolation of its constituent's volumes. Deviations from this description occur such that volumes are both greater and smaller than the linear relationship would predict. Here we use special quasirandom structures and density … WebThe deviation from Vegard's law for the changes in the [ital c] parameter of the solid solutions La[sub 2[minus][ital x]A[ital x]][sup [prime]]CuO[sub 4[minus][ital d]] ([ital A][prime]=Ba,Sr,Ca) is examined. When [ital d]=0, the changes in the [ital c] parameter are controlled in a linear manner (Vegard's law) by two factors: the size effects ...
