Previous investigators have shown gold rich Au-Pt alloys with the addition of small amounts of iron exhibit a definite change in mechanical properties as a function of iron content and heat treatment . However, the literature reveals little information concerning the mechanism by which these alloys harden. The object of this investigation was to observe the change in hardness values in gold rich Au-Pt-Fe alloys as a function of composition, aging time, and aging temperature. In addition, electron microscopy techniques have been employed in an attempt to explain the hardening characteristics in the gold-platinum-iron system.
