Structure and Compressive Properties of Silver Foams with Various Porosities
The sintering and dissolution process (SDP), in which NaCl is used as space holder, was used to produce open-cell Ag foams with various pore sizes. The content, size and shape of NaCl particles dictate the pore architecture of the foams. The yield strength of Ag foams decreases with increasing porosity. Of equivalent porosity, the yield strength of the foams with larger pore size is also higher than the foams with smaller pore size.
