Notes:
The starting material, the deformed state, as well as the recrystallised microstructure andtexture have been analysed as a function of Zener-Hollomon parameter and strain for twodifferently heat-treated AlMgSi alloys, deformed in torsion. An interesting and somewhatsurprising observation is that the grain size was always higher in the material heat treated to formlarge Mg2Si particles. Moreover, no indications of PSN effects were observed in any of thematerials, even at the highest Zener-Hollomon parameters. This observation was quite unexpectedas the highest Zener-Hollomon parameters were well above the typical critical level for whichsignificant PSN effects have been observed in similar alloys. The results have been carefullyanalysed and possible explanations are discussed
