a Integrated diffraction line profiles for AX61 in the as-extruded (green solid line), rotary swaged (blue solid line), conventionally annealed (purple solid line), and flash annealed (red solid line) states. Al2Ca peaks are observed in all four samples. Mg17Al12 peaks were found in the rotary swaged sample, but disappeared after flash annealing. b, c Bright field TEM images of an AX61-FA sample after 4% tensile strain, showing the interaction between <c + a> dislocations and Al2Ca precipitates. d FWHM of the \(\{10\bar{1}2\}\) peak at different tensile strains in AX61-RS (blue circles) and AX61-FA (red triangles).
