Effect of microalloying with rare-earth elements on the texture of extruded magnesium-based alloys

摘要

A series of alloys have been produced with microalloying additions of rare-earth (RE) elements in the range of 0.1-0.4 wt. percent. The alloys have been extruded to produce grain sizes of 23 +- 5 mu m. The texture of the extruded alloys was measured, and it was found that the extrusion texture was weakened by the addition of RE elements. The samples with weakened extrusion textures exhibited an increase in the tensile elongation.
