Abstract Scope |
The addition of Y and Zn can substantially improve the mechanical properties of Mg. Further alloying elements modify the secondary phases formed by the former, enabling to tailor the properties. Samples of pure Mg1.8Y0.6Zn and modified with 1.6 wt.% Gd, 1 wt.% Ag or 0.4 wt.% of Ca, were subjected to in situ tensile testing at the Dual Imaging And Diffraction beamline, Diamond UK, with a strain rate of 10-3 s-1, 10-4 s-1 and 10-5 s-1. During testing, tomographies were acquired to follow the crack initiation and evolution in 3D and diffraction patterns alongside the acoustic emission signal from the samples were also recorded to track the microstructural changes, thus enabling a comprehensive description of the damage in the samples leading up to the failure. The results show that the additional alloying elements and the strain rate both have a significant effect on the damage process and the failure. |
