Title: Effect of Anisotropy on Microstructures and Mechanical Properties of Rolled Ti/Al/Mg/Al/Ti Laminates

Abstract

TA2/5052Al/AZ31/5052Al/TA2 five-ply laminates were fabricated by hot rolling, and the effect of anisotropy on their microstructures and mechanical properties was studied. After rolling, the Mg/Al and Al/Ti interfaces were both closely connected, but the interfacial shapes were totally different. For the Mg layer microstructures in the middle area, regardless of the direction, dynamic recrystallized (DRXed) grains appeared around the deformation bands. However, twins and a shear zone appeared in the RD sample; the twins decreased in the sample along the 45° angle, and no twins appeared in the TD sample. The Ti layer showed equiaxed grains in different directions, which were attributed to the ability of Ti alloy to anti-deform. The tensile testing results showed that the fracture of the Ti/Al/Mg/Al/Ti laminates can be divided into four stages. The laminate had an ultimate tensile strength of 434 MPa and excellent elongation along the rolling direction (RD), which were attributed to its DRXed grains and twins. In conclusion, the laminates had significant anisotropy due to the presence of Mg alloys.
