Abstract

The invention discloses a preparation method and application of an aluminum-based light high-entropy alloy metal powder cored welding wire. The aluminum-based light high-entropy alloy metal powder cored welding wire comprises a metal powder core and a metal sheath wrapping the metal powder core, wherein the metal powder core is alloyed high-entropy alloy powder, the metal sheath is an aluminum-based material, and the metal sheath accounts for 5-90% of the total mass of the metal powder core and the metal sheath. The preparation method comprises the following steps: carrying out cold rolling on an aluminum-based material to 0.1-2 mm, and then slitting the aluminum-based material to 5-15 mm in width; and then placing the metal powder core, grinding balls and a process control agent in a high-energy ball milling tank, and carrying out ball milling for 10-100 h. According to the invention, the aluminum-based light high-entropy alloy metal powder cored welding wire with low density and high performance is obtained by utilizing additive manufacturing technologies such as electric arc fuse, laser fuse and the like; the suitable aluminum-based high-entropy alloy component range is wide, and the precision and speed of part preparation can be controlled according to the thickness of the welding wire; the large light high-entropy alloy component can be prepared in the modes of electric arc additive manufacturing and the like, and size limitation is avoided; and a large component with excellent performance is obtained.

Description

technical field

[0001] The invention belongs to the technical field of high-entropy alloy materials, and relates to an aluminum-based light-weight high-entropy alloy and material-adding technology, in particular to a preparation method and application of an aluminum-based light-weight high-entropy alloy metal powder-cored welding wire. Background technique

[0002] Traditional lightweight materials are mostly Al alloys, but their performance can no longer meet the increasing performance requirements of materials in the fields of aviation, aerospace, electronics, and communications. Developing lightweight, low-cost structural materials with outstanding properties has always been difficult and is a challenge for many scientists today. Ceramic materials have extremely high hardness and strength under the condition of light weight, but their elongation is extremely low, and processing is difficult, making it impossible to make components with complex shapes.
