Abstract

The invention belongs to the field of laser additive manufacturing, and particularly relates to an aluminum alloy material and a laser 3D printing aluminum alloy component based on the same. A preparation method of the aluminum alloy material comprises the following steps that (s1) Al, Mn and Ti are evenly mixed to obtain a mixture, and by mass, the content of Mn is 1-8 parts, the content of Ti is 1-6 parts, and the content of Al is 84-98 parts; and (s2) after the mixture is melted, aluminum alloy powder is prepared with a gas atomization method and is dried to obtain the aluminum alloy material. According to the aluminum alloy material and the component, Mn and Ti elements are added, so that the processability and the mechanical property of wrought aluminum alloy which is originally not suitable for a laser 3D printing technology are remarkably improved, the developed alloy has extremely-high thermal stability, and residual stress generated in the 3D printing process can be relieved through very simple thermal treatment.

Description

technical field [0001] The invention belongs to the field of laser additive manufacturing, and in particular relates to an aluminum alloy material and a laser 3D printed aluminum alloy component based on the material. Background technique [0002] Aluminum alloy is an alloy with aluminum as the base and other alloying elements added. Aluminum alloy is light in weight, has good corrosion resistance, high specific strength and specific stiffness, and has good plastic processing properties, making it one of the most widely used structural materials. It has been widely used in automotive, aerospace, construction, and electromechanical fields. Laser 3D printing technology is a technology that uses high-energy lasers to selectively melt and solidify metal materials layer by layer according to preset files, and finally manufacture metal parts. Compared with traditional casting, forging and powder metallurgy technology, the most obvious advantage of laser 3D printing technology is ...
