A new amalgam alloy consisting of spherical particles having a composition of 60% Ag, 27% Sn, and 13% Cu was investigated by microprobe and X-ray diffraction analysis. The alloy seemed to consist of minute dispersion of Cu3Sn, gamma(Ag3Sn), and beta(Ag-Sn). Amalgam made from this alloy exhibited a matrix of gamma1(Ag-Hg) with small reaction phase areas of Cu6Sn5. No gamma2(Sn-Hg) was observed.
An analysis of the relationship between creep and microstructural characteristics of several gamma2-containing amalgams showed the grain size of the Ag-Hg phase (gamma1) to be a predominant factor influencing creep. When gamma1 grain size is increased, creep is reduced.
