摘要: Abstract The phase equilibria of the Mg–Ag–Cu ternary system at 350 and 400 °C were experimentally investigated using twenty-eight key samples. compositions in samples scanning electron microscopy (SEM) equipped with energy-dispersive spectroscopy (EDS). Powder X-ray diffraction (XRD) technique was used to analyze crystal structure solid solubility compounds. Five three-phase several two-phase have been determined 400 °C. range Cu compounds Mg3Ag, MgAg fcc(Ag) examined maximum Ag compound MgCu2 found be 11.46 at.% 11.25 a constant value about 66 400 °C, respectively. Besides, limits Mg2Cu fcc(Cu) less than 5 No observed present work.
