- 摘要：Hot ring rolling (HRR), a near-net-shape technology, was used to fabricate a large sized AZ80-Ag alloy ring at 653 K in this study. The microstructure, texture and mechanical properties of different regions within the HRRed ring wall were systematically investigated. The lowest level of plastic deformation and highest temperature are identified in the central region of the ring wall. Due to the influence of non-uniform distribution of strain and temperature, the deformed microstructure is inhomogeneous throughout the ring wall thickness. After rolling deformation, the spherical beta-Mg17Al12 precipitates are formed inside grains and along grain boundaries. The basal pole inclines and the {001}orientation spreads towards some particular directions depending on the sampling regions. Therefore, obvious anisotropy of mechanical properties was observed in various regions due to different basal slip Schmid factors in the tensile directions.
