| Résumé | This research examined in-situ creep behavior of three extruded high performance magnesium alloys (AE42, AJ32 and ZE10). Neutron diffraction was used to measure compressive creep behavior at 175°C in the extrusion direction. The AE42 and AJ32 alloys exhibited higher creep strains than the ZE10 alloy. The highest strain was recorded for AE42 (2.4 percent), while ZE10 exhibited greatest creep resistance (0.2 percent strain). Microstructure analysis has shown that the distribution and composition of secondary phases was critical for creep resistance. The aluminum containing alloys had acicular and globular intermetallics, whereas the ZE10 alloy contained fine and irregular intermetallics dispersed along grain boundaries, effectively contributing to pinning of grains under high temperature loads. Significant grain re-crystallization was also observed in the aluminum containing alloys, but was absent in ZE10. |
