Texture Weakening Effects in Ce-Containing Mg Alloys

High-speed extrusion of dilute Mg-Zn-Ca-Mn alloys and its effect on microstructure, texture and mechanical properties

“…5, direct evidence of PSN was not detected during extrusion. On the other hand, it is known that finely distributed stable particles can prevent the grain growth by restricting grain boundary migration through the Zener drag (or Zener pinning) effect [32][33][34]. According to the classical Zener drag theory [35], the grain growth stagnates when the driving pressure for grain growth is balanced by the particle induced pinning pressure at certain average grain size.…”

“…This grain size is named the Zener limited grain diameter (Dz), which can be classically expressed as [35]: (1) where f and r are the volume fraction and average radius of pinning particles, respectively. Zener pinning is expected to occur if D  Dz, but not if D  Dz [33,34].…”

Profile Shape Effect on the Texture and Mechanical Properties of Extruded Rare Earth Containing Magnesium Alloys

“…It can be noted that these alloys can be kept with the alloying elements in solid solution which is not possible in MN20 and MX21. Thus, the formation of this corresponding texture is not necessarily associated with any growth restriction of grains during recrystallization due to the formation of precipitates [20].…”

Microstructure, Deformation, and Property of Wrought Magnesium Alloys

“…Textures of sheets produced from binary Mg-RE alloys have been extensively studied using XRD and EBSD. [204,[231][232][233][234][235][236][237] These studies reported that the textures of the Mg-RE alloy sheets were similar to that of AZ31 except that their intensities were significantly weakened. The c-axes of most grains had broader distribution around the sheet normal direction.…”
