The microhardness of nanocrystalline Ag, synthesized by inert gas condensation and in-situ compaction, and the effects of both grain size and compacting pressure on the hardness were studied. The results show that the microhardnesses of all the nanocystalline Ag specimens compacted under the pressure range from 0.15 to 1.80 GPa are greater than that of polycystalline Ag. No effect of the strain...
