Abstract Scope |
Heat treatable 6082 aluminum alloy was subjected to several complex thermo-mechanical procedures including variations of rolling, accumulative roll bonding and heat treatment. The intention was to produce microstructure which will benefit from the combination of work- and precipitation strengthening. It was found that careful design of deformation route must be undertaken since non-cell forming alloy suppress precipitation due to relatively uniform distribution of dislocations after the rolling. In such a situation, dislocations attract solutes which cannot form strengthening phases. For this reason, a changes of rolling directions together with an interop heating were applied to promote low angle grain boundary formation instead. Strengthening curves course was altered when compared to undeformed material which indicate changes in precipitation occurrences. Combined EBSD and TEM investigation was performed to understand these variations in selected samples. |
