We studied the relationship between hardness, bending strength, structure, and oxidation zone. 1). The oxidation zone was formed on the alloy by heat treatment, exposure to air, and reduced pressure. The oxidation zone, was not formed on the alloy by heat treatment in the reducing agent. 2). As the copper and zinc in the alloy were selectively oxidized, age hardening of the oxidation zone did not occur. Alloy heat treatment in the reducing agent appeared to age harden. 3). Bending strength was affected by oxidation zone. The more the oxidation zone was increased, the more bending strength was decreased. 4). The bending stength of the high gold and palladium content alloy was superior to that of the heat treatment.}, pages = {208--217}, title = {金銀パラジウム合金の熱処理に関する研究}, volume = {14}, year = {1988} }
