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…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
