摘要
The effect of trace Ti and Y on Au-based alloys with 990 fineness has beeninvestigated systematically by means of tensile test, hardness test, scanning and transmissionelectron microscopic analyses. These experimental results show that trace Ti and Y can significantlyimprove the mechanical properties of Au-based alloys with 990 fineness because Ti and Y cansignificantly refine matrix grains, and solid solution strengthening, work strengthening andprecipitation strengthening occur during mechanical heat treatment.
