Deformation behavior and microstructure of Mg-13Gd-4Y-2Zn-0.5Zr alloy during the rotating forward extrusion process

Yali Duan et al.

Summary: This study proposed a new plastic deformation technique, rotating forward extrusion (RFE), for producing rare-earth (RE) Mg alloy bars. The results showed that the equivalent strain increased significantly and the equivalent stress continuously decreased during the RFE process. The metal streamline of the sample exhibited two different directions, and the grains were significantly refined while the basal texture was weakened.

Quasi-in-situ observing the rare earth texture evolution in an extruded Mg-Zn-Gd alloy with bimodal microstructure

M. G. Jiang et al.

Summary: This study investigated the static recrystallization and texture evolution in an extruded Mg-Zn-Gd alloy, providing direct evidence of rare earth (RE) texture evolution during grain growth. The research findings contribute to understanding the mechanisms involved in forming RE texture during extrusion and developing wrought Mg alloys with improved formability.

Unraveling the effect of deformation-induced phase transformation on microstructure and micro-texture evolution of a multi-axially forged Mg-Gd-Y-Zn-Zr alloy containing the LPSO phase

S. M. Ramezani et al.

Summary: This study comprehensively examined the effect of blocky to lamellar phase transformation on the microstructure and micro texture of a Magnesium-Rare earth alloy through multiaxial forging. The main reasons for achieving a very fine-grained microstructure were identified as particle stimulated nucleation and continuous dynamic recrystallizations. Additionally, two new rare earth texture components were formed during the second forging pass, but disappeared during the third pass due to the suppression of PSN by the phase transformation.
