Description
Technical field
The present invention relates to a kind of welding new material, belong to the Materials Science and Engineering field.
Background technology
High-strength aluminum copper alloy is widely used at aerospace industry, is aircraft fuel tank, the top-priority material of rocket tank, and external similar material has been widely used in aircraft fuel tank, the manufacturing of rocket tank.Domestic high-strength aluminum copper alloy is used comparatively and is lagged behind, in recent years along with the development of aerospace industry, schedule is mentioned in the application of high-strength aluminum copper alloy, yet the application of high-strength aluminum copper alloy be unable to do without solder technology, and this just proposes the development problem of homemade high-strength aluminum bronze aluminium alloy adapted welding wire.The existing ripe adapted welding wire-aluminum bronze series solder wire of high-strength aluminum bronze aluminium alloy that foreign country is similar, aerospace industry has been used for many years abroad, adopt U.S.'s aluminum bronze series solder wire to weld, institute's plumb joint mechanical property meets design requirement, and the problem of existence is that weld porosity sensitiveness is bigger.The domestic existing aluminum bronze series solder wire that is suitable for the normal temperature use, but its cryogenic property is relatively poor.
Summary of the invention
The object of the present invention is to provide a kind of welding wire that is applicable to high-strength aluminum copper alloy, this welding wire cooperates with high-strength aluminum copper alloy, and applicable to the needs that aircraft fuel tank, the welding of rocket tank are produced, its weld seam can obtain high normal cryogenic mechanics performance.
The welding wire that is applicable to high-strength aluminum copper alloy of the present invention, its chemical composition are (wt%): Cu 5.8～6.8, Mn0.2～0.4, Ti0.05～0.2, Zr 0.05～0.25, V0.01～0.20, and Cr 0.01～0.25, and Fe 0.15, Si 0.08, and Zn 0.05, Mg0.02, and surplus is Al.Adopt traditional founding refining welding wire by prescription.
Welding wire design of chemical composition principle of the present invention is to adopt the mode of polynary composite alloying, thereby reaches the optimum Match of welding wire and mother metal, and promptly chemical composition, physicochemical property are suitable, make the high combination of strength and toughness of weld seam acquisition.The present invention adopts traditional founding refining welding wire, because it is alloy that high-strength aluminum copper alloy belongs to Al-Cu-Mn, so Al-Cu-Mn system is adopted in the decision of welding wire principal component, the microalloy composition removes and adopts Ti, Zr, outside the V, add Y respectively, Ce, Sc, Cr, B, in refining process, pass through to adjust the content of each alloy, adopt different compound modes: Ti-B, Ti-B-Y, Ti-Zr-Sc, Ti-Zr-V-Ce, Ti-Zr-V, Ti-Zr-B, Ti-Zr-V-Y, Ti-Zr-V-Sc, Ti-Zr-V-Cr, Ti-Zr-V-B, refine out welding wire, carry out the crack sensitivity evaluation then, the stomata sensitivity evaluation, joint is (normal temperature under different temperatures,-196 ℃,-253 ℃) the mechanical property evaluation, the adaptability evaluation of different thicknesss of slab, the metallographic structure evaluation, the fracture apperance evaluation, through some round tests, finishing screen is selected satisfactory welding wire, and the prescription of this welding wire both had been the prescription of final welding wire.
Owing to adopt above-mentioned prescription to make welding wire of the present invention, so the present invention has following advantage and effect:
1, the present invention is because employing Al-Cu-Mn is a master alloying system, and Ti-Zr-V-Cr is the microalloy composition, and the control of impurity elements such as Fe, Si, Zn, Mg is tighter, so welding crack sensibility is lower.
2, the present invention has inhibitory action owing to contain the Cr trace element to aluminium alloy weld seam pore, add the welding wire hydrogen content and be controlled at below the 0.2ml/100g metal, so weld porosity sensitiveness is little.
3, the present invention contains 0.01-0.25Cr, and the control of impurity elements such as Fe, Si, Zn, Mg is tighter, and Cr has tangible invigoration effect during welding, and the negative effect of impurity controls to minimum, so the joint performance excellence.
