Abstract

The invention discloses a high-strength alloy for three-dimensional printing and a preparation method thereof. The mass percentages of the components of the alloy are: 6~18wt.%Gd, 0.5~4wt.%Er, 0.5~4wt.%Y, 0.2 ~1wt.%Ca, 0~1wt.%Zr, the balance is Mg and unavoidable impurities. The preparation method is as follows: after designing the composition, the raw materials are made into spherical powder, and the metal powder is fully mixed, the mixed raw material powder is sintered and solid solution heat treated, and then the alloy spherical powder is obtained through mechanical grinding and alloying. The finished product obtained by three-dimensional printing has the advantages of high flame retardancy, light weight, high strength and wear resistance.

Description

technical field [0001] The invention belongs to the technical field of 3D printing materials, and in particular relates to a high-strength alloy for 3D printing and a preparation method thereof. Background technique [0002] 3D printing technology, also known as additive manufacturing according to its manufacturing process, belongs to a kind of rapid prototyping technology. It uses powdered metal or plastic and other bondable materials, and finally prints directly Produce products and form "digital manufacturing". 3D printing technology originated from the photographic sculpture and landform forming technology researched in the United States at the end of the 19th century, but limited by the technical conditions at that time, no breakthroughs were made. In the 1980s, with the vigorous development of computer technology and new material technology, 3D printing technology has made great progress, but its commercialization and marketization process is slow. In the 21st centur...
