Modeling of mechanical behavior of ultra fine grained aluminum produced by multiple compressions in a channel die
سال
: 2012
چکیده: Mechanical behavior of AA1100 aluminum alloy processed by multiple compressions in a channel die
was modeled on the basis of a generalized three-dimensional dislocation-density-based two-phase composite
model. The simulated yield stress values were compared with the experimental data obtained by
the multiple compressions in a channel die after several passes. A good agreement was found between
the experimental and simulated yield stress values. The results showed that the yield stress of the ultra
fine grained materials, produced by multiple compressions in a channel die, can reasonably be simulated
using a dislocation-density-based two-phase model. Moreover, the experimentally determined average
grain size of the studied material correlates well with that predicted by the model. Therefore, it can be
said that the dislocation-based model could be used to predict the average grain size of the multiple compressed
materials in a channel die.
