    Notes: In this study, specimens of a high-copper amalgam, prepared at different final Hg contents, were examined in several different experiments. The results showed that as the Hg content is increased, a point is reached beyond which creep and the amount of Sn in γ1 exhibit a sudden increase. As the Hg content is increased further, γ2 can be detected. These phenomena can be explained by the hypothesis that insufficient Cu is present at higher Hg contents to combine with Sn to form Cu6Sn5.

    Behavior of three high-Cu amalgamsPresented at the 1978 Meeting of the International Association for Dental Research, Washington, D.C. (1979)

    Notes: Amalgams made from three single-composition high-Cu alloys of the same nominal composition were investigated for differences in creep behavior. The curves of creep vs. final Hg content for all three alloys showed a sudden creep increase (jump) at approximately 46% final Hg content. Previous studies have shown this creep jump to be associated with the initiation of the Sn—Hg phase (γ2). The anticipated final Hg content in clinical restorations for two of these alloys is below the creep jump and γ2 would not be expected. On the other hand, the clinical Hg content for the third alloy was above its creep jump and γ2 would be expected. The effect on clinical behavior of this finding requires further investigation.
