abstract = {The prospects of metal injection molding (MIM) technique
for manufacturing of highly porous titanium parts was
studied by physical modeling, based on feedstock warm
compaction experiments. The space holder method and typical
MIM binder were used in all cases of the study. The
influence of the starting powder (dehydrided and atomized)
in feedstock on resulting properties of porous titanium was
investigated. The size of space holder particles and space
holder amount were adjusted to obtain porosity and pore size
desired for medical implants application. NaCl and KCl were
studied and compared as prospective space holder materials.
The porous samples were characterized regarding their
microstructure, uptake of interstitial contents and
mechanical properties. For comparison, same investigations
have been conducted on samples, which were prepared by
established space holder technology based on cold isostatic
pressing (CIP) and sintering. Finally, first direct MIM
experiments and attempts of feedstock optimization were
carried out. The peculiarities and problems of metal
injection molding of highly porous titanium have been
discussed.},
