Abstract: The paper presents the experimental results concerning the
elaboration by mechanical alloying (MA) of some Fe nanopowders alloyed
with 3% Mn, 1% Mo, 1.5% Cr and 0.5% B. These nanopowders will be used as
master-alloys to process PM low alloyed sintered steels. The influence of
the milling time of the fine grinding of the powder particles on the
morphology and distribution of the alloying elements in the nanoparticles
powders was analyzed. It is proved that the transition from the
micrometric to the nanometric range of the particles is of 40 hours and
after 60 hours the alloying elements have a homogeneous distribution in
the powder particles. |
