Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below.

[0025] A high-entropy flux-cored wire for titanium-steel MIG welding, including powder and sheath.

[0026] The powder is prepared by the following components in atomic percentage, the total atomic percentage is 100%, among which Fe 5~15%, Ti10%~20%, Co 20%~30%, Cr 18%~35%, Ni 20%~35% %, Cu 5%~13%;

[0027] The outer skin material is industrial high-purity copper tape (99.99%) with a width of 10±0.1mm and a thickness of 0.5±0.04mm.

[0028] The preparation method of the above-mentioned high-entropy flux-cored welding wire is implemented according to the following steps:

[0029] Step 1. Fusion Master Alloy

[0030] According to the composition of atomic percentage (see Table 1), the total atomic percentage is 100%, convert the atomic percentage into mass percentage, and weigh various high-purity metals (99.99%) according to the mass percentage; put the above metal materials in a ball m...

Abstract

The invention discloses a high-entropy flux-cored wire used for titanium-steel MIG welding. The high-entropy flux-cored wire used for titanium-steel MIG welding is prepared by following components including, by atomic percent, 5 to 15% of Fe, 10 to 20% of Ti, 18 to 25% of Co, 20 to 35% of Cr, 21 to 35% of Ni and 5 to 13% of Cu, wherein the total percent of the components is 100%. An industrial high pure copper strip is adopted in a skin material. The preparing method comprises the steps of firstly, smelting and matching of a mother alloy; secondly, applying of a vacuum gas atomization powder making technology to prepare atomized powder; thirdly, adopting of a flux-cored wire forming unit device for making the high-entropy flux-cored wire. The high-entropy flux-cored wire is used for carrying out titanium-steel MIG welding, an excellent titanium-steel welding joint is obtained, chemical components of welding line metal are in the main element range of a high-entropy alloy, and high-entropy of the welding line is achieved. The welding line has the excellent strength and toughness, the brittle intermetallic compound is effectively removed, and the comprehensive mechanical performanceis good.

Description

technical field [0001] The invention belongs to the technical field of welding, and relates to a high-entropy flux-cored welding wire for titanium-steel MIG welding and a preparation method thereof. Background technique [0002] In recent years, due to the increasingly serious energy problems and environmental problems, the urgent requirements for lightweight products have been put forward in the manufacturing industries such as aircraft, automobiles, trains, and ships, as well as in the fields of energy, aerospace, and national defense. Titanium and titanium alloys play an important role in the process of lightening products by virtue of their low density and high specific strength. The weight of titanium-steel composite parts is equivalent to 50~60% of steel, and it also has other excellent characteristics of titanium and steel. It has obvious social effects and economic benefits, and has good application and development prospects. However, the use of titanium and steel ...
