“…An example of the underdeveloped texture during such torsional processes is the weakening of the major torsion texture after passing through an intensity peak upon continuous single direction torsion 26 . It is therefore apparent that, although torsion may produce much higher strain levels than rolling, the torsion texture appears to be relatively weaker by contrast to the heavy rolling texture 27 .…”

A stable {$$\stackrel{\mathrm{-}}{1}{\text{10}}$$ 1 - 10 } <110> single component sharp texture was obtained during ambient temperature tube High-Pressure Shearing (t-HPS) of 99.999% purity aluminum. It is shown that the grain size and the grain aspect ratio saturate at ~ 8 μm and ~ 1.6, respectively, at an equivalent strain of ~ 30 and the high-angle grain boundary fraction continues to decrease after this saturation even to equivalent strains exceeding ~ 200. The {$$\stackrel{\mathrm{-}}{1}{\text{10}}$$ 1 - 10 } <110> texture emerges at an equivalent strain of ~ 6 to 9 with the completion of recrystallization and develops gradually as a sole component sharp texture with increasing intensity upon further processing. This component is a stable orientation in t-HPS processing although it was not previously observed experimentally as a shear texture. Thus, t-HPS processing provides a new and effective experimental tool for simple shear testing that is distinctly different from earlier shear strain methods such as torsional processing.

“…The performance and corrosion resistance of Al-Mg alloy are improved by the increase of element magnesium in the alloy, and the tensile strength can be enhanced to a superior level. Al-Mg alloy with high magnesium content would become a competitive material in the future [4][5][6]. However, some cracks appear in in last freeze of Al alloy flat ingots after casting, which exceeds the reasonable amount of saw waste.…”

In casting of Al-Mg alloy, especially in the aluminum alloy with high Mg content of more than 4 wt.% Mg, some cold cracks were found in last freeze of the flat ingots. The depth of cracks was bigger than 200 mm. The size of scrap removal of ingot was thus increased by 70 mm or more, and the yield of the flat ingots was greatly affected. Air cooling time of more than 20 min after casting was a better to reduce cracks in last freeze of Al-Mg alloy flat ingots.
