Abstract Scope |
In-situ neutron and synchrotron X-ray diffraction (XRD) experiments were performed on an AZXM2110 (Mg-2Al-1Zn-1Ca-0.3Mn) Mg alloy to investigate deformation mechanisms during room-temperature tensile deformation. During the early stages of deformation, in-situ neutron diffraction results showed a micro yielding that was activated at 0.1 % strain by basal slips. Tensile deformation beyond micro-yielding was dominated by basal and other non-basal slips with limited extension twinning. In-situ synchrotron XRD measured texture illustrated that the as-rolled sample had a strong basal texture. Tensile deformation along rolling direction (RD) developed {10-10}//RD and {11-20}//TD texture, as well as {0002}//ND slightly spreading towards TD. Further microstructure analysis and numerical modeling will be conducted to quantitatively investigate the dislocation types and activities of various deformation modes. |
