Effect of Ce, Sm and Sr micro-alloying on the microstructure, mechanical properties and anisotropy of rotated rolled Mg–4.5Al–1.5Sn–0.5Ca–0.2Mn alloy
Mg–Al series sheets usually exhibit an apparent mechanical anisotropy induced by strong basal texture. In this study, a near-isotropic Mg–4.5Al–1.5Sn–0.5Ca–0.2Mn (ATXM5210) alloy was developed via 0.05 wt.% Sr micro-alloying combined with rotated rolling, displaying an ultra-low difference in yield...

| description | Mg–Al series sheets usually exhibit an apparent mechanical anisotropy induced by strong basal texture. In this study, a near-isotropic Mg–4.5Al–1.5Sn–0.5Ca–0.2Mn (ATXM5210) alloy was developed via 0.05 wt.% Sr micro-alloying combined with rotated rolling, displaying an ultra-low difference in yield strength (∼5 MPa), ultimate tensile strength (∼2 MPa) and elongation (∼1 %) between the rolling direction (RD) and transverse direction (TD), in contrast to a strong anisotropy of Sr-free alloy. We comparatively investigated the effect of trace Ce, Sm and Sr addition on the microstructure, texture evolution and mechanical properties of rolled ATXM5210 alloy. Specially, Sr-containing alloy possesses a more uniform distribution of finer CaMgSn particles after rolling, whereas coarse particles and particle bands are still distinctive in Sr-free alloys. Furthermore, the addition of Sr contributes to form broader-distributed texture towards both RD and TD with reduced peak intensity (∼10.8), leading to an apparently reduced mechanical anisotropy. The quite low mechanical anisotropy and balanced combination of yield strength (∼220 MPa) and ductility (∼21 %) make the present ATXM5210-0.05Sr alloy suitable for producing intermediate or final products and competitive for various engineering applications. |
