Abstract:Addition of trace Zn can impose notable effect on the deformation behavior of Mg‐Gd‐Y‐Zr alloy, while the underlying mechanisms have not been revealed. In the present work, Mg‐8.5Gd‐2.5Y‐0.3Zr (wt%) (0Zn) and Mg‐8.5Gd‐2.5Y‐0.5Zn‐0.3Zr (wt%) (0.5Zn) alloys were fabricated by casting and extrusion, to obtain a bimodal microstructure containing fine DRXed grains and coarse unDRXed grains. The as‐extruded 0Zn and 0.5Zn alloys were studied by in‐situ synchrotron diffraction under uniaxial tension and compression to… Show more
