EFFECTS OF HEAT TREATMENTS ON CAST GOLD ALLOY. PREHEATED FURNACE OR SALT BATH AT 450 DEGREES F PRODUCES OPTIMUM HARDNESS AND STRUCTURAL UNIFORMITY,
Abstract
Specimens of cast gold alloy were subjected to various methods of heat treatment, to determine the effects upon microstructure and hardness. Hardness of the heattreated specimens was determined with a Tukon tester, using a Knoop indenter. Variations in microstructure were studied by metallographic and photomicrographic examinations. Measurements were made of the temperature generated during grinding and polishing of cast gold. (Author)
