Abstract Scope |
There is currently a significant scientific and industrial interest in developing material models for the simulation of aluminum extrusions relevant to forming and their in service response. The objective of this work is to evaluate the effect of through thickness crystallographic texture gradients on material mechanical behaviour. This has been studied using a combination of experiments and the VPSC polycrystal plasticity simulations. Two limiting conditions were examined, i.e. unrecrystallized and fully recrystallized structures. The results revealed a significant through thickness variation in texture for both cases. Although the implications of the texture gradient on the macroscopic plastic response were relatively minor for the unrecrystallized case, they were quite significant for the recrystallized condition. This was manifested as a strong difference in the contraction of the surface layer compared to the centre of the extrudate, particularly in the case of tests at 45 ° and 90 ° to the extrusion direction. |
