Abstract
A study of the effect of solute substitution in the 52.5 at.- % gold-cadmium alloy, at an electron concentration of 1.475, has been made to determine the stability of the β′ phase in the presence of elements of various atomic and ionic size, valency, and electronegativity. From the data presented, it appears that an explanation of β′-phase stability in terms of other than a complex interaction of these parameters is not possible.
