The Effect of Reciprocating Extrusion (Cec) on the Consolidated Silver Powders Microstructure / Wpływ Dwustronnego Wyciskania (Cws) Na Mikrostrukture Konsolidowanych Proszków Srebra

The microstructure and properties investigations silver powders consolidated by cyclic extrusion compression (CEC) were performed. The AgSnBi and AgNi powders using for electrical contacts were investigated. The observation by using optical microscopy (MO) and transmission electron microscopy (TEM) were apply. The strong diminishing of microstructure inside the consolidated granules were found. This phenomenon cause microhardness increase, restricted by material porosity.
