In the present study, the age-hardenability of various Au-Cu-Zn alloys containing Pd at intraoral temperature was evaluated by means of hardness test and X-ray diffraction (XRD) study after solution-treatment at various temperatures and then aging at intraoral temperature. The apparent age-hardenability of Pd-free AuCu-20Zn (at%) alloy (specimen 1) at intraoral temperature resulted from the formation of the AuCu Ⅱ ordered phase, and the age-hardenability at intraoral temperature became apparent with increasing solution-treatment temperature. The age-hardenability of the Au-Cu-Zn alloys containing Pd at intraoral temperature decreased with increasing Pd content. The alloy containing 10 at% Pd did not show age-hardenability at intraoral temperature even with Zn addition up to 20 at%. The alloy containing 5 at% Pd showed relatively apparent age-hardenability at intraoral temperature, which resulted from the atomic diffusion by the help of quenched in excess vacancies. The low e/a-value (electrons per atom) of Pd was thought to be the reason for the inhibition of the AuCu Ⅱ phase formation in the Au-Cu-Zn alloys containing Pd.
