Abstract
The invention discloses an aluminum alloy containing scandium, titanium and zirconium elements for 3D printing. The aluminum alloy comprises the following components in percentage by weight: 1.5%-4.5%of Mg, 1%-3.5% of Mn, 0.2%-1.5% of Sc, 0.2-1% of Ti and Zr in total, 0.0001-0.15% of O, impurities, and the balance Al. Compared with an existing aluminum alloy for 3D printing, the aluminum alloy has the advantages that the Ti element in the alloy can replace the strengthening effect of the Sc element to a certain extent so as to improve the economical efficiency, the Ti element in the alloy canreplace the strengthening effect of the Zr element to a certain extent so as to reduce the preparation difficulty of the alloy, and the alloy has excellent mechanical properties and good forming characteristics.
Description
technical field [0001] The invention relates to the technical fields of aluminum alloy and 3D printing, in particular to an aluminum alloy for 3D printing containing scandium, titanium and zirconium elements. Background technique [0002] Metal material 3D printing technology has great advantages in the preparation of complex structural parts. It can directly process special models such as complex inner cavities and lattice structures, providing more design space for structural designers and industrial designers. At present, the 3D printing technology of metal materials is mainly carried out around the existing alloy grades. The common stainless steels for 3D printing are 304, 316L and 17-4PH, etc. The common titanium alloys for 3D printing are TC4, TC6 and TA12. Alloys include GH4169, GH3625, and GH3536, etc. Common aluminum alloys for 3D printing include AlSi7Mg, AlSi10Mg, and AlSi12. It can be seen that most of the common 3D printing alloys are existing grades in traditi...
