| Özet |
| In this work, phase selection, microstructure and mechanical properties of Mg-Al-Ca-Mn alloys with three different Ca/Al ratios (0.58, 0.79 and 0.91) were studied. The Mn content of the alloys was kept constant at ∼0.30 wt%. Thermodynamic non-equilibrium (Scheil) simulations, X-Ray Diffraction (XRD) analyses and Scanning Electron Microscopy/Electron Dispersive Spectroscopy (SEM/EDS) determined that all three alloys contain α-Mg solid solution phase, Al8Mn5 intermetallics and, depending on the Ca/Al ratio, combinations of C36-(Mg,Al)2Ca (hP24 a = 0.577–0.586 nm, c = 1.819–1.835 nm), binary C14-Mg2Ca (hP12, a = 0.620 nm c = 1.023 nm), ternary C14-Mg2Ca (hP12, a = 0.561–0.599 nm, c = 1.025–1.051 nm), and/or C15-Al2Ca (cF24, a = 0.793 nm) Laves phases. It is observed that Ca/Al ratio shows a direct relationship with the total amounts of Laves intermetallics and the … |
