Creep and phase transformation in dental amalgam.
Creep measurements were performed on different types of amalgams as a function of heat treatment after specimen preparation before testing. The types of amalgams included lathecut, spherical, nonpreamalgamated amalgams, and an amalgam containing Ag-Cu particles. Heat treatment significantly reduced the creep of all alloy types studied. Creep reduction was associated with the phase and transformation gamma1 leads to beta1 (Ag-Hg), which was detected by metallographic and microprobe analysis.
