Abstract
The present disclosure provides Au-based alloys comprising Si capable of forming metallic glass matrix composites, and metallic glass matrix composites formed thereof. The Au-based metallic glass matrix composites according to the present disclosure comprise a primary-Au crystalline phase and a metallic glass phase and are free of any other phase. In certain embodiments, the metallic glass matrix composites according to the present disclosure satisfy the 18-Karat Gold Alloy Hallmark.
Claims18
A Au-based metallic glass matrix composite comprising Si in the range of atomic fraction of 1 to 16 percent, and consisting essentially of a primary-Au crystalline phase and a metallic glass phase.
