Influence of Extrusion Ratio on Microstructure and Tensile Properties of Mg–Gd–Y–Zn–Zr Alloy
In the present work, an Mg–5Gd–4Y–0.5Zn–0.5Zr alloy was extruded at 450 °C with three extrusion ratios of 25, 79 and 178. The microstructure of the as-cast and as-extruded specimens were analyzed by using Opti...

Phase Equilibria in the Al-Zr-Nd System at 773 K
The isothermal section of the phase diagram of the Al-Zr-Nd ternary system at 773 K has been investigated by means of x-ray powder diffraction (XRD), scanning electron microscopy (SEM) and optical microscopy (...
