Decreasing the mechanical anisotropy of the forged Mg-8.5Gd-2.5Y-1.5Zn-0.5Zr alloy by modulating blocky LPSO particles using multi-directional forging

Journal of Magnesium and Alloys
The blocky LPSO particles were modulated by single-directional and multi-directional forging, and the effect of blocky LPSO particles on the anisotropy of mechanical properties of Mg-8.5Gd-2.5Y-1.5Zn-0.5Zr alloy forged parts was investigated.
