In the present study, the age-hardenability at intra-oral temperature of various Au-Cu-Zn alloys containing Ga, Ti, Sn, Cr was evaluated by means of hardness test and X-ray diffraction (XRD) study after solution-treatment at various temperatures and then aging at intra-oral temperature. By the addition of Ti and Sn, the age-hardenability at intra-oral temperature of Au-Cu-Zn alloys decreased apparently. And by the addition of Ga and Cr, the apparent age-hardenability at intra-oral temperature of Au-Cu-Zn alloys was preserved. In Cr-added Au-Cu-Zn alloys, the reduction of Cu content rather than Zn content was much more effective for preserving the age-hardenability at intra-oral temperature. The apparent age-hardenability at intra-oral temperature of Ga- or Cr-added Au-Cu-Zn alloys attributed to the formation of the AuCu Ⅱ ordered phase. In the Au-Cu-Zn alloys containing Cr, the increased Cr content did not prevent the formation of AuCu Ⅱ ordered phase at intra-oral temperature, but possibly reduced the driving force for the formation of AuCu Ⅱ ordered phase at intra-oral temperature. If Ga- or Cr-added Au-Cu-Zn alloy having apparent age-hardenability at intra-oral temperature is used as a dental alloy, it will become harder in the oral cavity without additional heat-treatment.
