Abstract

Change in the microstructure of the L10-type ordered β′phase precipitated in Ag-20Pd-12Au-14.5Cu alloy (mass%) subjected to solution treatment with varying solution treatment time was investigated. The size of the β′phase is found to decrease with increasing solution treatment time and the Vickers hardness of the alloy after solution treatment decreases. Experimental observations show that the microstructural change of the β′phase strongly contributes to the change in Vickers hardness. In addition, the formation and growth of the β′phase are concluded to be affected by the distribution of elements through solution treatment.
