Description

6 is body of a motor car with high baking hardenability aluminum alloy materials
Technical field
The present invention relates to a kind of 6 line aluminium alloys, relate in particular to a kind of 6xxx and be body of a motor car, belong to the aluminium alloy technical field with high baking hardenability aluminum alloy materials with higher baking hardenability.
Background technology
The automobile lightweight is one of developing direction of automobile, and the aluminium alloying of automobile then is light-weighted important means.In recent years, the exploitation of body of a motor car aluminium alloy plate is the emphasis of studying both at home and abroad always, and it mainly concentrates on 2xxx system, and 5xxx system and 6xxx are three big series.But development trend is that exploitation 6xxx is the car body panel aluminium alloy at present.
This is that alloy is usually with the T4 (solution hardening+natural aging) or the supply of material of T4P (solution hardening+preageing) state.This material of general requirement yield strength before automobile factory's punching press is lower, work hardening rate and unit elongation are higher, thereby provide good forming property, pressed part obtains higher intensity by ageing strengthening in last baking vanish process, have higher shock resistance in the process under arms to guarantee the auto sheet material.The vehicle body plate that obtains at present to use mainly contains AA6111 alloy, AA6016 and AA6022 aluminium alloy with the 6xxx line aluminium alloy.Domestic problem owing to the automobile board drawing can not be properly settled also can't carry out the suitability for industrialized production of body of a motor car with 6xxx line aluminium alloy plate, and the calorize rate of domestic automobile car body panel is zero substantially.
Domestic research to the 6xxx line aluminium alloy at present mainly concentrates on the AA6111 alloy.AA6111 alloy baking hardening is better, but the yield strength before its punching press higher (usually surpass 150MPa even higher), causes this material forming degradation, flange ductility relatively poor, is difficult to all satisfy the plasticity requirement of vehicle body plate.The Cu content of this alloy is higher simultaneously, has reduced the corrosion resisting property of material.6016,6022 alloys have forming property preferably, but relative 6111 alloys of its baking hardenability are low for low Cu alloy.
Therefore the 6xxx line aluminium alloy of a kind of low Cu of needs exploitation, and this alloy has higher baking and hardening performance simultaneously, satisfies the needs of forming property, becomes the key issue of body of a motor car developing material.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing body of a motor car with aluminium alloy capability, use on the basis of al alloy component at existing vehicle body, by the adjustment of alloying constituent, provide that a kind of to take into account preferably the 6xxx of baking and hardening performance and forming property be body of a motor car with high baking hardenability aluminum alloy materials.
Purpose of the present invention is achieved through the following technical solutions:
6 is body of a motor car with high baking hardenability aluminum alloy materials, the quality percentage composition of composition is: Si0.50~1.00wt%, Mg 0.60~1.30wt%, Cu 0.01~0.30wt%, Mn 0.05~0.20wt%, Cr≤0.10wt%, Ti≤0.15wt%, Fe 0.05~0.25wt%, surplus is Al.
Further, above-mentioned 6 is body of a motor car with high baking hardenability aluminum alloy materials, wherein, Si 0.50~0.75wt%, Mg 0.60~0.80wt%, Cu 0.10~0.30wt%, Mn 0.05~0.10wt%, Cr≤0.10wt%, Ti≤0.15wt%, Fe 0.05~0.15wt%, surplus is Al.
Further, above-mentioned 6 is body of a motor car with high baking hardenability aluminum alloy materials, and wherein, the quality percentage composition of magnesium is greater than 1.3-0.66 * Si, Mn 0.10~0.20wt%, Fe 0.15~0.25wt%.
Above-mentioned 6xxx be body of a motor car with high baking hardenability aluminum alloy materials, behind the casting, carry out homogenizing annealing thermal treatment, hot rolling then, cold rolling, solution treatment; Natural aging one day at least before drawing.Yield strength before its punching press is lower than 130MPa; And behind the baking vanish yield strength greater than 230MPa, tensile strength greater than 310MPa.This material has higher baking and hardening performance, and its processability satisfies processing request.
Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:
The present invention controls the content of main alloy element Mg, Si, Cu in the 6xxx line aluminium alloy, makes material have higher baking and hardening performance, guarantees that simultaneously material has higher work hardening capacity, forming property; The reasonable content of control micro-Fe, Mn on the other hand with the grain-size of control material etc., thereby reaches the purpose that the material forming performance further is provided.The multiple technologies measure guarantees that material has better comprehensive mechanical property, is the ideal material of making body of a motor car, better satisfies the service requirements of automobile technology.
Embodiment
At existing commercial with body of a motor car with 6 line aluminium alloys or intensity is lower, the present situation of forming property relatively poor (especially yield strength is too high before the punching press), by the content of reasonable each alloying element of adjustment, take into account the purpose of forming property and baking hardenability preferably to reach.
The present invention 6 is a body of a motor car with high baking hardenability aluminum alloy materials, the quality percentage composition of composition is: Si 0.50~1.00wt%, Mg 0.60~1.30wt%, Cu 0.01~0.30wt%, Mn0.05~0.20wt%, Cr≤0.10wt%, Ti≤0.15wt%, Fe 0.05~0.25wt%, surplus is Al.The ideal composition proportion is: Si 0.50~0.75wt%, and Mg 0.60~0.80wt%, Cu0.10~0.30wt%, Mn 0.05~0.10wt%, Cr≤0.10wt%, Ti≤0.15wt%, Fe0.05~0.15wt%, surplus is Al.The quality percentage composition of magnesium is greater than 1.3-0.66 * Si, Mn 0.10~0.20wt%, Fe 0.15~0.25wt%.
Mg, Si element are the main alloy element in the 6xxx line aluminium alloy, and its content and ratio have not only determined the strength level (baking vanish performance) of material, have also determined the forming property of material.When Mg was higher in the material usually, the work hardening exponent of material was higher, and forming property is better.But the Mg too high levels, L appears in punch components surface easily, thereby influences the surface quality of parts; In the 6xxx line aluminium alloy, contain excessive Si element usually (with respect to equilibrated Mg 2The Si composition), to increase baking hardenability.But the Si element is crossed and form excessive Mg at most easily in tissue 2Si or superfluous Si particle, this moment, the intensity of material can not be improved, and occurred the phenomenon that forming property descends on the contrary; Cu is the main purpose that improves baking hardenability that rises in the 6xxx line aluminium alloy.But the Cu too high levels then reduces the corrosion resisting property of material.Therefore as Si 0.50~1.00wt%, when Mg 0.60~1.30wt%, Cu0.01~0.30wt%, material can have higher baking and hardening performance, can have higher forming property and corrosion resisting property again.
Mn, Fe element are main trace additives, and purpose is the grain-size of control material.The content of Mn is 0.05~0.20wt%, Fe 0.05~0.25wt%.Mn, Fe content are low excessively, do not reach the purpose of control grain-size, too highly then form a large amount of thick compounds, thereby reduce the forming property of material.As Si 0.50~0.75wt%, during Mg 0.60~0.80wt%, Mn can be 0.05~0.10wt%, and Fe is 0.05~0.15wt%.Guaranteed the effect of crystal grain thinning on the one hand, avoided too much Mg, Si element to combine on the other hand, thereby reduced strengthening effect with Mn, Fe element; Work as the mass percent of the quality percentage composition of magnesium in the material simultaneously greater than 1.3-0.66 * silicon.Because Mg, Si constituent content are more, superfluous Mg may appear in the material 2The Si phase, the forming property of reduction material.This moment, Mn, Fe element can be the upper limit of its content, i.e. Mn 0.10~0.20wt%, and Fe can be 0.15~0.25wt.%.Higher Mn, Fe content can consume the unnecessary Mg of part, Si element, and form second phase of control grain-size.
Cr should guarantee smaller or equal to 0.1wt% simultaneously; Ti then can further guarantee the forming property of material smaller or equal to 0.15wt%.
More than the alloy of Huo Deing behind the casting, carries out homogenizing annealing thermal treatment, hot rolling then, cold rolling, solution treatment, and natural aging is more than 1 day, and its yield strength is lower than 130MPa; And behind the baking vanish yield strength greater than 230MPa, tensile strength greater than 310MPa.
