dc.description.abstract | Additively manufactured (AM) aluminium alloys have attracted increasing attention due to the great demand of prototyping, spare parts supply, short run productions and further light-weighting of vehicles. However, most of the reported AM aluminium alloys are usually modified version of commercial cast or wrought aluminium alloys. In this work, we successfully developed a new high-strength and ductile Al5Mg3Zn2Si alloy, which is designed for laser powder bed fusion (LPBF) process. The optimized relative density of 98.9% was obtained at a volumetric energy density (VED) of 129.1 J/mm3. The as-LPBFed Al5Mg3Zn2Si alloy features refined equiaxed α-Al grains and Al–Mg2Si eutectic network. In addition, the sub-micrometre sized, coherent α-Al(Fe,Mn)Si and MgZn2 dispersoids in conjunction with high number density of (Mg,Zn)-rich GP zones co-contribution to the excellent combination of mechanical properties, i.e. the ultimate tensile strength of 548 MPa, the yield strength of 403 MPa, and the elongation of 6.7%. Such a high-strength and ductile AM aluminium alloys without any addition of costly alloying elements has a great potential for automotive and aerospace applications. | - |
