摘要	Abstract This paper focuses on researching the formation mechanism of mesh eutectic textures of AlSi7Mg manufactured by selective laser melting (SLM) and the relationship between the evolution of the eutectic Si structure and mechanical properties with ageing temperature. The microstructure of AlSi7Mg could be analyzed with the help of the scanning electron microscope (SEM), different thermal analysis (DTA), x-ray diffraction analysis (XRD). After a suitable heat treatment process, the strength of AlSi7Mg manufactured by SLM can surpass 440MPa. The article describes the relationship between microstructures and mechanical properties, which provides a basis for heat treatments for other researchers. The major outcome of this paper, it could help to formulate a heat treatment with high elongation or high strength for SLM AlSi7Mg. This article describes the reason for the formation of the mesh eutectic Si texture. It is believed that the fine mesh eutectic Si texture is the unique advantage of SLM technology over casting or forging technology.
