Background
With the development of science and technology, the requirements of the fields of aerospace, weapon manufacturing and the like on materials are increasingly strict. In particular, structural materials for equipment in the field of automobile and aircraft engines not only require the materials to have precise and complex overall structures, but also require the materials to have relatively high mechanical properties under normal temperature and high temperature service. In various material forming technologies, compared with the traditional casting and extruding process, the laser additive manufacturing technology can form structural parts with complex shapes and can greatly improve the mechanical property of metal components. Therefore, laser additive manufacturing technology is becoming a key molding technology in the field of new material preparation and manufacturing.
However, aluminum alloy samples obtained by laser additive manufacturing and forming often have many defects due to the defects of poor flowability, high laser reflectivity, easy oxidation and the like of aluminum, and aluminum alloy powder which is currently available for laser additive manufacturing is mainly concentrated in Al-Si alloys. Such as hypoeutectic and eutectic Al-Si alloys containing 7 wt% Si to 10 wt% Si, have good fluidity and improved laser absorption due to the addition of Si element.
