Abstract

The invention discloses a highly plastic and corrosion-resistant Zn-Cu-Ti alloy and a preparation method thereof. The high-plasticity corrosion-resistant Zn-Cu-Ti alloy is composed of the following components in weight percentage: Cu1.3%~1.6%, Ti0.03%~0.06%, Mg0.001%~0.003%, La0.08%~ 0.12%, the balance is Zn. The above-mentioned high-plasticity and corrosion-resistant Zn-Cu-Ti alloy is prepared by smelting the alloy raw material, then performing horizontal continuous casting, pre-deformation and single-pass hot rolling. In this alloy, the proportion of alloy components is reasonable, pre-deformation and single-pass rolling improve the rolling efficiency, refine the crystal phase, and reduce the generation of defects; the tensile strength and elongation of the alloy reach 309.338MPa, 35.6 %, compared with the specified value of the EN988 European standard, the strength and corrosion resistance of the alloy are improved without sacrificing the plasticity of the material.

Description

technical field [0001] The invention belongs to the field of Zn-Cu-Ti alloys, in particular to a Zn-Cu-Ti alloy with high strength, high plasticity and corrosion resistance and a preparation method thereof. Background technique [0002] my country is a country poor in copper and rich in zinc. In recent years, with the rapid development of copper processing in my country, domestic copper resources can no longer meet the needs of production. 70% of domestic raw material copper comes from imports, and the bottleneck of copper resource supply has become increasingly obvious. Give full play to the advantages of zinc resources in my country, develop high-performance zinc alloy materials, promote their industrial production and large-scale application, and realize "replacing copper with zinc" in a wider range of fields, which can further reduce the contradiction between domestic copper resource demand and supply, and is in line with national industry requirements. development policy...
