Detailed Description
The present invention will be further described with reference to the following examples for better understanding of the present invention, but the embodiments of the present invention are not limited thereto.
A high-performance 6-series aluminum alloy comprises the following components in percentage by mass: mg 0.5-0.95 wt%; cu 0.5-1.8 wt%; mn is less than or equal to 0.15 wt%; si 0.6-1.4 wt%; cr is less than or equal to 0.06 wt%; ti is less than or equal to 0.04 wt%; zn is less than or equal to 0.05 wt%; fe is less than or equal to 0.15 wt%; the balance of Al and inevitable impurities.
Mg and Si are main strengthening elements in 6-series aluminum alloys, and they form a strengthening phase Mg2 Si. Generally, the higher the content of Si and Mg, the larger the volume fraction of Mg2Si, the higher the strength of the material. At the same time, however, excessive addition of Si and Mg elements also causes a large amount of Mg2Si phase, i.e., a poorly soluble phase, to be formed in the material, which exceeds the solid solubility of the matrix, thereby causing a reduction in the appearance of the material due to anodic oxidation (e.g., a reduction in brightness after highlighting the anode). Therefore, the contents of Si and Mg need to be limited to: 0.6-1.4 wt% and 0.5-0.95 wt%. In addition, the Si/Mg ratio also has a large influence on the precipitation of Mg2Si, the precipitation of a strengthening phase is facilitated when the Si/Mg ratio is large, the material is easier to extrude and obtains a stronger quenching effect, so that the concentration of supersaturated solid solution and vacancies in the matrix is large, the material has a large age hardening potential, and the ratio is limited to 1-2.5.
Cu is a main additive element in 6-series aluminum, generally plays roles in improving solid solution strengthening effect, reducing room temperature parking effect and improving strengthening phase precipitation kinetics, but the content of Cu is not too high, otherwise, the extrusion deformation resistance is increased and the corrosion resistance of the material is reduced, so the content of Cu is limited to 0.5-1.8 wt%.
Mn, Cr and Ti are trace elements, and are helpful to the grain control of the material. The content of the element is not too much, otherwise, the interaction of the element causes the grain structure to have fibrous structure, thereby causing the anode oxidation to have defects of material veins, different colors, mottles and the like; therefore, the contents of the four elements need to be controlled as follows: less than or equal to 0.15 wt% of Mn, less than or equal to 0.06 wt% of Cr, less than or equal to 0.04 wt% of Ti and less than or equal to 0.15 wt% of Fe.
Zn is an impurity element in the 6-series aluminum alloy, and the content of Zn is controlled to be less than 0.05 wt%.
The preparation process of the high-performance 6-series aluminum alloy comprises the following steps: after the temperature is preserved for 6-20h at the temperature of 480-; extruding the homogenized material, wherein the rod temperature is 500-560 ℃, and the outlet temperature of the extruded material is 500-550 ℃; aging of the extruded materialKeeping the temperature at 80-120 ℃ for 4-24h, and then heating to 170-190 ℃ for 4-12 h; wherein the purpose of the homogenizing annealing is to eliminate Mg formed during casting2The elimination of the Si phase needs a certain temperature and heat preservation time to be eliminated. The adoption of the two-stage homogenization process is more beneficial to the dissolution of the coarse second phase. The homogenized material is extruded, the rod temperature and the extrudate exit temperature are controlled to promote Mg2The dissolution of Si and the retention material have a higher vacancy concentration. The above effect can be achieved within the temperature range, over-high temperature easily causes over-burning and material scrapping, over-low temperature cannot achieve the purposes of dissolving and promoting vacancy formation, and the outlet speed of the extruded material can be more than 8 m/min due to good component configuration of the material. The two-stage aging process is adopted in the aging process, so that the strengthening phase Mg2Si is fully precipitated, and the effect of improving the strength of the material is achieved.
Through the components and the process measures, the brightness of the material after the anode is more than or equal to 550 Gu; the yield strength of the material is more than 400 Mpa.
