title: Segregation in precious-metal dental-casting alloys.
abstract: The aim of this study was to conduct a theoretical analysis of segregation in Au-Ag-Cu and Ag-Pd-Au-Cu dental-casting alloys, and to confirm and extend the results experimentally. Both theoretical and experimental data showed greater segregation in the Ag-Pd-Au-Cu alloy than in the Au-Ag-Cu alloy. There was very little segregation of gold, zinc, and platinum, while between the dendrites copper increased and silver and palladium decreased.
