The fabrication of porous shape memory alloys is analyzed based on the particularities of the alloy families and the spacer materials potentially to be used for pores generation. The analysis is made for two distinct set of shape memory alloy families Cu-based and Ti-based, taking into account solid state sintering technologies. Sodium chloride, magnesium and carbamide are comparatively analysed for the use in the fabrication of the porous shape memory materials. Particularities in using spark

Experiments performed on alloys belonging to the shape memory system are analyzed from macro and microstructural point of view in order to assess the influence on the resulting functionality. The results allowed the selection of the optimal processing parameters for the fabrication of porous alloys.
