Abstract

The injection molded Fe sintered bodies were fabricated using two kinds of nano Fe powders, $Fe-5%vol.ZrO_2$ and $Fe-10vol.%ZrO_2$ powders. The relationship between microstructure and mechanical properties depending on the $ZrO_2$ contents and sintering temperature were characterized by SEM and TEM techniques. In the wear test, the $Fe-0vol%ZrO_2$ sintered bodies showed mainly adhesive wear, but in the Fe-5%vol. $ZrO_2$ and Fe-10vol. % $ZrO_2$ composites the main wear behavior showed abrasive wear mode.
