Experimental study and thermodynamic assessment of the Al-Sc-Zr system

摘要：

　　The joint addition of Scandium and Zirconium could significantly improve the mechanic properties of Aluminum alloys due to the formation of Al3Sc phase with Ll2 structure.It is thus extremely important to have a thorough understanding of the phase equilibria of Al-Sc-Zr ternary system.Employing equilibrated alloys,the isothermal section of this system at 873 K has been determined by means of scanning electron microscopy (SEM) equipped with energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD).
