| Abstract Scope |
Al-Mg alloys for 3D printing, alloyed with strengthening elements, have advantages for application in various industries (automotive, aviation and space, tooling and consumer goods) due to their attractive levels of mechanical characteristics and corrosion resistance. Scandium remains the most effective additive in aluminium alloys, increasing the yield strength and the material processability. However, Sc is an expensive alloying element which addition in the amount of 0.1% wt. increases the total cost by at least 2 times.
In the present work the scientific approaches for development of Al-Mg based materials for using in laser powder bed fusion (LPBF), economically alloyed with Sc, as well as with full replacement of Sc are presented. The advanced analysis of mechanical properties and corrosion behavior was carried out. The specific features of structure formation were discussed. The opportunities to use topological optimization, LPBF-process modeling to design new parts for various applications are presented. |
