Texture tailoring and bendability improvement of rolled AZ31 alloy using {10–12} twinning: The effect of precompression levels
In this study, the texture of a rolled Mg alloy is effectively modified through the application of precompression and subsequent annealing treatment, leading to a remarkable improvement in the bending formability of the alloy at room temperature. Precompression induces lattice reorientation through...

| description | In this study, the texture of a rolled Mg alloy is effectively modified through the application of precompression and subsequent annealing treatment, leading to a remarkable improvement in the bending formability of the alloy at room temperature. Precompression induces lattice reorientation through {10–12} twinning, and annealing treatment reduces the stored strain energy of the precompressed material, which results in the formation of a stable grain structure with two dominant texture components. With an increase in precompression, the tensile strain in the outer region of the bending samples is accommodated to a greater extent due to more pronounced {10–12} twinning and basal slip. As a result, the bending formability of the material at room temperature improves with greater precompression. The variation in microstructure, texture, and bending behavior in relation to the degree of precompression is discussed in detail. Keywords: Magnesium, Bending, Formability, Twinning, Texture |
