Structure transormations during annealing of twin-roll cast Al-Fe-Mn-Si (AA 8006) alloy sheets. I. Effect of cold rolling and heating rate

Original language description

The kinetics and temperature range of structure transformations occurring during annealing of twin-roll cast AlFeMnSi (AA 8006) alloy sheets were studied using thermoelectric power (TEP), electrical resistometry, light metallography, and transmission electron microscopy. The effects of cold rolling before heat treatment and of the heating rate were investigated. Both influence the onset and the kinetics of solid solution decomposition and the recrystallized grain size. The solid solution decomposition starts. at 340°C in the sample cold-rolled with 96 % reduction. It is more intensive above 430°C in the material deformed to 33 % only. The non-equilibrium eutectic phase of the as-cast material fully transforms into individual particles ofthe cubic alfa-Al(Fe,Mn)Si, orthorhombic Al6(Fe,Mn) and monoclinic Al3Fe phases. The annealing above 510°C leads to particle coarsening and partial re-dissolution of particles. This is an indirect evidence that dissolved Fe, Si and Mn atoms are still pr
