The mechanical anisotropy of Mg-Zn-Y alloys with columnar crystals in specific orientation J. Alloys Compd. (IF 5.8) Pub Date : 2024-07-04 D.R. Fang, H. Zhang, X.P. Lin, Y.W. Guo, X.Z. Zhang, Q.Z. Gao
The MgZnY alloys were prepared by directional solidification, and the effect of loading modes on mechanical anisotropy and deformation mechanism of the alloys was studied. The microstructure of the alloy is columnar crystals whose growth orientations are mainly concentrated in <110>. When the tensile load is parallel to longitudinal grain boundaries of columnar crystals, the alloy has high yield strength
