MEDICAL AU-PT-PD ALLOY

The present invention relates to a medical Au-Pt-Pd alloy including Au, Pt, Pd, and inevitable impurities. The alloy has an alloy composition inside a polygon (A1-A2-A3-A4-A5-A6) surrounded by straight lines connected at point A1 (Au: 37.9 atom%, Pt: 0.1 atom%, and Pd: 62 atom%), point A2 (Au: 79.9...

Beschreibung
Zusammenfassung:	The present invention relates to a medical Au-Pt-Pd alloy including Au, Pt, Pd, and inevitable impurities. The alloy has an alloy composition inside a polygon (A1-A2-A3-A4-A5-A6) surrounded by straight lines connected at point A1 (Au: 37.9 atom%, Pt: 0.1 atom%, and Pd: 62 atom%), point A2 (Au: 79.9 atom%, Pt: 0.1 atom%, and Pd: 20 atom%), point A3 (Au: 79.9 atom%, Pt: 20 atom%, and Pd: 0.1 atom%), point A4 (Au: 69.9 atom%, Pt: 30 atom%, and Pd: 0.1 atom%), point A5 (Au: 49 atom%, Pt: 30 atom%, and Pd: 21 atom%), and point A6 (Au: 39 atom%, Pt: 40 atom%, and Pd: 21 atom%) in a Au-Pt-Pd ternary state diagram. The metal structure of the alloy is optimized, and the metal structure is close to a single-phase structure, and has little precipitation of a Au-rich phase and a Pt-rich phase different in composition from a mother phase.
