Abstract

An extruded Mg–1Mn–1Nd (wt%) (MN11) alloy was tested in tension in an SEM at temperatures of 323K (50°C), 423 K (150°C), and 523 K (250°C) to analyse the local deformation mechanisms through in situ observations. Electron backscatter diffraction was performed before and after the deformation. It was found that the tensile strength decreased with increasing temperature, and the relative activity of different twinning and slip systems was quantified. At 323K (50C), extension twinning, basal, prismatic (a) and pyramidal (c+a) slip were active. Much less extension twinning was observed at 423K (150ºC) while basal slip and prismatic (a) slip were dominant and presented similar activities. At 523K (250ºC), twinning was not observed, and basal slip controlled the deformation.
