The ordering and precipitation phenomena responsible for hardening of gold-based alloys used in jewellery and in dentistry are complex and by no means fully understood. The authors of this article review these effects and present evidence which indicates that separation of gold-zinc intermetallic phases may contribute to such hardening in certain alloys.
