Thermal Stability of Cryomilled Al-Mg-Er Powders

Figure 10

Indexed SAED patterns from the large grained regions shown in Figure 9: Al grains viewed from (a) B = direction at 180°C, (b) B = direction at 330°C, and (c) B = direction at 500°C; (d) second-phase particles observed in powders annealed at 330°C. The small circles indicate the spot diffraction pattern and rings (indicated by arrows) are produced by nanoscale phases in the imaged regions.
