| Abstract Scope |
Ni-Al bronze is widely used in marine applications due to combination of good mechanical properties and corrosion resistance. Recent studies showed that the mechanical properties of this material system can be further enhanced by using WAAM additive manufacturing (AM). However, there is still a knowledge gap in understanding of the effect of the AM microstructure on the deformation mechanisms, especially strain localization. Our work focuses on the detailed multi-scale characterization of the WAAM processed Ni-Al bronze in relation to monotonic tensile properties. As-deposited microstructure is studied as well as that after deformation combining SEM-SE, BSE, FIB, EBSD techniques with STEM and EDS. Strain localization and crack initiation is studied on the samples strained close to YS and UTS. Key microstructural aspects and deformation mechanisms are identified and discussed related to the performance of the material. |
