A previous study of the effect of final Hg content on the static creep of a single-composition high-Cu amalgam alloy showed a sudden increase or jump in creep at a specific Hg content, and the presence of the Sn-Hg phase (gamma 2) at final Hg contents subsequent to this creep jump. This observation is consistent with the less-than-optimum clinical performance reported for this alloy. A repetition of these tests conducted on test specimens 3 months and 6 months of age showed the creep jump to shift to higher Hg contents. However, even at 6 months of age, the final Hg content to be expected in clinical restorations was still positioned after the initiation of the creep jump where a small amount of gamma 2 is known to be present.
先前一项关于最终汞含量对单一成分高铜汞合金静态蠕变影响的研究表明，在特定汞含量下蠕变会突然增加或跃升，且在此次蠕变跃升之后的最终汞含量下存在Sn-Hg相（γ2）。这一观察结果与该合金报告的欠佳临床性能相符。对3个月龄和6个月龄的测试样本重复进行这些测试，结果显示蠕变跃升向更高汞含量偏移。然而，即便在6个月龄时，临床修复体中预期的最终汞含量仍处于蠕变跃升开始之后的位置，已知此时存在少量γ2相。
