Abstract Scope |
One of the major problems associated with additive manufacturing (AM) of metallic parts is the formation of columnar/directional grains that gives a significant mechanical anisotropy in the structural part. Columnar grains form due to multiple melting and solidification cycles during AM process and also due to the lack of suitable nucleation sites, where new grains can form dynamically if the conditions are met. Addition of carefully chosen nano-particles (~1 vol%) during the AM process may work as nucleation sites by a mechanism called particle stimulated nucleation (PSN). In this study, cubic boron nitride nanoparticles have been added during the additive manufacturing of AlSi10Mg alloy. Microstructural evaluation was investigated by optical and scanning electron microscopes and the phases were identified by X-ray diffraction (XRD) and Electron Probe Micro Analyzer (EPMA). |
