Hot rolling textures of f.c.c. metals. Part 1: Experimental results on Al single and polycrystals
- Ecole des Mines de Saint Etienne (France). Microstructures and Processing Lab.
The influence of deformation temperature on the hot rolling textures of aluminum alloys has been investigated by channel die compression tests on Al-1%Mg-1%Mn polycrystals and oriented single crystals in the temperature range 200--400 C. Quantitative texture measurements on the polycrystalline samples demonstrate a substantial increase in the {l_brace}110{r_brace}<1{bar 1}2> ``Brass`` component at higher temperatures together with a small but significant amount of ``near-Cube`` orientations. These texture variations with temperature occur in the absence of recrystallization. The single crystal experiments show that these textures can be related to the onset of non-octahedral slip in Al and Al-1%Mn under hot working conditions of high strains and medium strain rates. The ``near-Cube`` orientations tend to be stabilized by slip on {l_brace}110{r_brace} planes while the ``brass`` orientation undergoes a substantially reduced {epsilon}{sub 12} (in-plane) shear. This behavior is predicted by a rate sensitive crystal plasticity model assuming {l_brace}111{r_brace} and {l_brace}112{r_brace} slip in accordance with the experimental results at 400 C.
