Abstract
The production of highly porous parts from titanium, stainless steel, and n ickel-based superalloys is of increasing interest in lightweight constructi ons. A new space-holder method uses carbamide (urea) and ammonium hydrogen carbonate to produce samples with porosities between 60 and 80%. Depending on the shape and size distribution of the space holder, spherical and angul ar pores in the range of 0.1-2.5 mm were obtained.
