Abstract

In this study, we reported the microstructure and properties of Ag-SnO_2 contact materials fabricated by a controlled milling process with subsequent consolidation. The milled powders were consolidated to bulk samples using a magnetic pulsed compaction process. The nano-scale SnO_2 phases were distributed homogeneously in the Ag matrix after the consolidation. The relative density and hardness of the Ag-SnO_2 contact materials were 95~96% and 89~131 Hv, respectively.
