Texture and mechanical behavior evolution of age-hardenable Mg–Nd–Zn extrusions during aging treatment

Three magnesium alloys containing different Nd and Zn were extruded and heat treated. The addition of Nd gives rise to the RE texture (c-axis oriented at an angle lower than 90° to the extrusion axis) in extruded Mg rods, reducing yield strength, improving tension–compression asymmetry and enhancing ductility. The Zn addition, on the other hand, weakens the RE texture by rotating the c-axes of the grains away from the extrusion axis, and also …
