Abstract

The material used in this study was AlSi10Mg alloy powder. And the particle morphology, particle size distribution and chemical properties of the aluminum alloy powder were characterized. The AlSi10Mg alloy powder was used for selective laser melting (SLM) forming. The SLM processes were conducted under the same process parameters, for example, material powder layer depth, scanning interval, and different volume energy density. The interaction between volume power density and organizational performance of the forming parts was analyzed through the density test, hardness test, and microstructure observation. It was found that the properties of forming parts by SLM was fine when the volume energy density was 50–80 J/mm3. Finally, suitable parameter of volume energy density for SLM manufactured AlSi10Mg alloy was confirmed, and the high density and hardness aluminium alloy forming parts were confirmed by SLM.
