EBSD measurements of Surfalex HF (AA6016A)

This dataset contains electron back scatter diffraction (EBSD) measurements of Surfalex HF (AA6016A), an aluminium alloy commonly used in automotive applications.<br> <br> The measurements were carried out using an FEI Sirion field emission gun scanning electron microscope equipped with a Nordlys detector from Oxford instruments. An acceleration voltage of 20 kV was used to scan large areas with a working distance of 16 mm and a step size of 2 μm. The size of the areas ensured that a sufficient number of grains were captured in order to have a reliable estimate of texture.<br> <br> EBSD scans were performed on three different planes with respect to the rolling (RD), transverse (TD) and normal (RD) directions: RD-TD, RD-ND and TD-ND. The sample preparation for EBSD involved grinding steps from 600 to 4000 grit, followed by 3 μm and 1 μm diamond polishing. The final stage of polishing was performed using a colloidal silica with a particle size of 0.02 μm. In order to increase the surface quality, the samples were then subjected to electropolishing using a solution of 70% methanol and 30% nitric acid. The electrolyte was maintained at -15 Celsius during the entire process. The polishing voltage was 10 V and the polishing time was 10 s.
