Origin of Internal Stresses in 18 cts Gold Alloys

In certain 18cts gold alloys thermo-mechanical processing may induce internal stresses resulting in undesired effects such as shape changes, cracking and failure. It is anticipated that the build-up of residual stresses in the gold alloys is directly related to the formation of the ordered AuCu phases.

The goal of this project is to establish a link between internal stresses in 3N and 5N 18 cts gold alloys at various stage of their processing steps in order to determine understand its origin and suggest paths to reduce residual stresses during manufacturing.
