This paper will investigate the diffusion reactions between two systems: 18K yellow gold to platinum alloys and 14K yellow gold to 14K palladium white gold. Physical, mechanical and crystallographic data will be determined for each diffusion bond and used to determine suitable heat treatments for the mokumé gane jeweler to avoid or to minimize the formation of brittle phases. The result will be to minimize process failures and maximize billet yields through heat treatment, forging and rolling to provide stock dimensions suitable for making jewelry.
