N2 - This study examined the microstructural, mechanical, and corrosion behaviors of a multidirectional-forged (MDF) Mg-Zn-Ca alloy. The results showed significant grain refinement of the alloy after 5 passes of the MDF process from 378μm to 23μm. X-ray diffraction analysis (XRD) revealed the presence of finer Mg7Zn3 phases and α-Mg and Ca5Zn3 phases after the MDF process and peak shift and broadening. Higher hardness (76.46±3) was noticed in the MDF 3 pass sample due to grain refinement; further hardness slightly decreased due to texture softening. Moreover, the results of the in vitro corrosion experiments conducted in SBF solution showed that the corrosion current densities of the alloys move in a noble direction as the number of MDF passes increases. MDF 3 pass sample (0.00523 mm/y) showed the lowest degradation rates compared to the as-cast sample (0.01154 mm/y), attributed to refining and redistributing the second phases.
