Fabrication of aluminium foam through pressure assisted high frequency induction heated sintering dissolution process: an experimental observation

A process based on powder metallurgy approach was developed to produce open celled aluminium foam. In the preparation of foam specimens, the Al powder and the NaCl (leaching agent) were dry mixed together in order to prepare a homogeneous mixture. The blended mixture was then subjected to pressur...
