High energy milling of ductile metals is difficult because of their flattening tendency under milling deformation. These powders are easily cold welded to each other and get flattened. Therefore, to ensure their continuous fragmentation is a complex process which needs optimization of milling parameters and in most cases it is necessary to add process control agents. Silver is a good example having above mentioned difficulties. In this study high energy milling behavior of Ag powders was studied under different milling conditions. Milled powders were characterized via XRD, BET, LPS measurements and SEM observations for the optimization of the milling conditions for achieving continuous fragmentation of Ag powders leading fine powders.
