Micro-alloying Mg with Y, Ce, Gd and La for texture modification-a comparative study
TL;DR: A comparative study of the effectiveness of Y, La, Ce and Gd as texture modifiers during the extrusion of magnesium-based alloys has been carried out in this paper, where it was found that Y was not as effective as the other three elements in modifying the texture, and at no concentration studied did this element form a typical rare earth texture.
