FEM modeling on the compaction of Fe and Al composite powders
The compaction process of Fe and Al composite powders subjected to single action die compaction was numerically modeled by FEM method. The relationship between the overall relative density and compaction pressure of the compacts with various Al contents was firstly identified, and the influ...

| description | The compaction process of Fe and Al composite powders subjected to single
action die compaction was numerically modeled by FEM method. The relationship
between the overall relative density and compaction pressure of the compacts
with various Al contents was firstly identified, and the influences of Al
content on the local relative density, stress, and their distributions were
studied. Then the compaction pressure effects on the above properties with
fixed Al content were discussed. Furthermore, detailed flow behaviors of the
composite powders during compaction and the relationship between the
compaction pressure and the ejection force/spring back of the compact were
analyzed. The results show that: (1) With each compaction pressure, higher
relative density can be realized with the increase of Al content and the
relative density distribution tends to be uniform; (2) When the Al content is
fixed, higher compaction pressure can lead to composite compact with higher
relative density, and the equivalent Von Mises stress in the central part of
the compact increases gradually; (3) Convective flow occurs at the top and
bottom parts of the compact close to the die wall, each indicates a different
flow behavior; (4) The larger the compaction pressure for each case, the
higher the residual elasticity, and the larger the ejection force needed. |
