摘要: The eutectic phase in a 1.72 mass pct calcium added AM50 die-cast alloy homogenized at 673 K has been investigated by X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). XRD EDS experiments indicate that the consists of Al2Ca with C15 structure contains 10.76 atomic magnesium equilibrium state. solubility lobe lies parallel to equi-66.7 at%Al composition line Mg-Al-Ca ternary grid, indicating preferentially substitutes site phase.
