Abstract: SummaryGold-lO% platinum alloys with additions of minor amounts of iron exhibit age hardening characteristics. Maximum hardness and maximum hardening rate occurred in gold-lO% platinum alloys containing 0.16 wt% iron. Electron microscopy t,echniques employing replicas of Au-Pt-Fe alloys revealed intragranular and intergranular precipitation phenomena occuied in the overaged condition. Electron diffraction and x-ray diffraction methods showed the intergranular phase to be an ordered face-centered cubic structu…
