抄録

In order to establish a standard for commercially available high functional gold alloys for clinical applications, a diversified study on the effects of softening and hardening heat treatment on the mechanical properties, including Vickers hardness, tensile strength, and the elongation of five commercial high functional gold alloys, was carried out. The commercial high functional gold alloys studied were Carrara H (CA), Degunorm (DE), DG/VO 8 (DG), Pontor LFC (PO), and Mainbond EH (MA).<BR>The results were as follows:<BR>1. Vickers hardness of these five commercial high functional gold alloys when cast ranged form 163 to 183 HV, while Vickers hardness of these five commercial high functional gold alloys after softenig and hardening heat treatment ranged from 122 to 148 HV and 182 to 208 HV, respectively.<BR>2. Tensile strength of these five gold alloys when cast ranged from 51.5 to 63.32 kg f/mm<SUP>2</SUP>. Tensile strength of these five gold alloys after softening and hardening heat treatment ranged from 36.8 to 54.32 kg f/mm<SUP>2</SUP> and 58.2 to 67.62 kg f/mm<SUP>2</SUP>, respectively.<BR>3. The elongation of these five gold alloys when cast ranged from 4.1 to 11.1%. The elongation of these five gold alloys after softening and hardening heat treatment ranged from 6.2 to 19.4% and 3.1 to 5.3%, respectively.
