Short-term stress relaxation of four dental amalgam alloys was studied. Test materials included two conventional lathe-cut restoratives, a spherical alloy, and a dispersed phase product. Specimens were 24-hr-old 4 X 8-mm cylinders. The specimens were compressed and held a t constant strain on develo

## Abstract The behaviour of AgβSn alloy and AgβSnβHg dental amalgam alloy has been studied under potentiostatic conditions in artificial saliva and in sodium chloride solutions containing 0.2% NaCl (alone or mixed with sodium hydrogen phosphate). It has been shown that Sn and Ag as well as the int
## Abstract Dental amalgams are based on a broad spectrum of materials differing in their chemical composition, metallurgical treatment, and in the way the initial alloys powders are prepared. In addition to their chemical composition, amalgams based on various powders differ in both their microstr
