Description
Technical Field
The invention relates to the technical field of aluminum alloy, in particular to a forming method of aluminum alloy.
Background
The thermal deformation-quenching composite process is to complete the formation of the material simultaneously in the heat treatment process, combine the heat formation and the heat treatment to complete in the same process step, and realize the purposes of forming and shaping by means of the same set of dies. Any heat treatment method for strengthening alloy by heating can be used for forming by using the heating process, so that strengthening and heat distortion limitation can be realized and the forming performance can be improved. At present, a high-strength steel and aluminum alloy composite forming technology mainly exists.
Compared with cold stamping, the high-strength steel plate hot stamping has obvious advantages, such as small deformation resistance and low requirement on equipment tonnage; the forming limit is high, the forming is easy, and parts with more complex shapes can be formed; quenching is completed in the die, and the dimensional accuracy of the formed part is high; the strength of the formed part is high by matching with a proper heat treatment mode.
However, aluminum alloy hot stamping belongs to high temperature forming, and the obtained member has lower strength and low dimensional stability. In mass production, the solid solution time and aging time are too long, resulting in low production efficiency. The disadvantage of hot stamping is that the strength of the aluminum alloy is low and the corrosion resistance is poor due to high temperature forming, and surface scratches are easily formed in the plate transferring and forming process to influence the surface quality, and additional heat treatment is required to be added to enable the formed part to obtain high strength. The time required for aging heat treatment is too long, and the method is not suitable for stacking heat treatment of stamping parts.
Therefore, there is a need to develop a method of forming aluminum alloys that matches the heat treatment of stamping.
Disclosure of Invention
The present invention aims to solve the above-mentioned technical problems existing in the prior art. Therefore, the invention provides a forming method of aluminum alloy, and the forming precision, strength, corrosion resistance and production efficiency of the prepared aluminum alloy are all obviously improved.
The invention also provides application of the aluminum alloy prepared by the forming method in aluminum alloy forming parts.
According to one aspect of the present invention, there is provided a method of forming an aluminum alloy, comprising the steps of:
s1, cooling an aluminum alloy material to-200 to-100 ℃ at a cooling rate of 100-150 ℃/s, preserving heat, and then stamping and preforming,
the pressure maintaining time in the stamping step is 5-20 s;
s2, heating the preformed aluminum alloy to 300-450 ℃ at a heating rate of 10-30 ℃/s, performing hot stamping, cooling to room temperature,
the pressure maintaining time in the hot stamping step is 10-30 s;
s3, pre-aging the aluminum alloy cooled in the step S2, cooling to-200 to-100 ℃ at a cooling rate of 100-150 ℃/S, heating to 120-200 ℃ at a heating rate of 10-30 ℃/S, and preserving heat for 10-60 min, so as to obtain a nonferrous metal material;
the application field of the nonferrous metal material is the field of automobile profiles.
The beneficial effects of the invention are as follows:
the ultra-low temperature forming, the high temperature forming and the cryogenic heat treatment are organically combined through the synergistic matching of the ultra-low temperature stamping preforming (step S1), the high temperature stamping final forming (step S2) and the cryogenic/heat treatment (step S3), so that the high strength, the high toughness, the high corrosion resistance and the high production efficiency of the hot formed aluminum alloy are realized, the solution treatment is not needed before the forming, the aging treatment is not needed after the forming, the production time is greatly shortened, and the production efficiency is remarkably improved.
The aluminum alloy material in the step S1 is cooled to the temperature of minus 200 to minus 100 ℃ at the cooling rate of 100-150 ℃/S, so that dislocation reinforcement of the aluminum alloy material is obtained, the low-temperature forming performance of the aluminum alloy material is ensured, and the cooling rate is controlled mainly to avoid defects of microcracks and the like in the material due to overlarge local stress caused by cold impact in the alloy due to the fact that the cooling rate is too high. The too slow cooling rate of lattice contraction promotes the lower elastic strain energy accumulated by the microstructure of the alloy, the number of generated dislocation is smaller, the energy provides lower driving force for the precipitation of the second phase in the heating process, the precipitation strengthening is not facilitated, and the dislocation strengthening and the precipitation strengthening are weakened.
The good forming performance of the aluminum alloy material is ensured at the heating temperature and the heating speed in the step S2, the forming performance is prevented from being reduced due to the fact that the temperature is too low, the solid solution softening is prevented from being caused by the fact that the solid solution temperature is exceeded, and the problems of deformation, thermal cracking and insufficient element diffusion caused by the fact that the heating speed is too high or too low are avoided at the heating speed.
In step S3, the above cooling rate avoids excessive dislocation and subgrain boundary formation caused by too fast or too slow cooling rate, which results in increased brittleness, cracking, etc., so that the strength and hardness of the material cannot achieve the desired effect.
The cooling rate avoids excessive phase transformation and dislocation formation in the aluminum alloy material caused by too high or too low heating rate, thereby reducing the plasticity and toughness of the material, and also avoids insufficient diffusion of solute elements in the aluminum alloy, so that the strength and hardness of the material cannot achieve the expected effect.
The heat preservation time avoids the second phase precipitation and insufficient dislocation formation in the aluminum alloy material caused by overlong or excessively short heat preservation time, thereby influencing the size and the number of the second phase and the number of the dislocation of the material, and further reducing the plasticity and the toughness of the material.
The invention combines ultralow temperature stamping preforming and high temperature stamping final forming, solves the problems of long solid solution time, short transfer time, serious temperature drop and poor surface quality of the aluminum alloy material, improves the strength of the aluminum alloy material due to a large amount of dislocation and lattice distortion in the ultralow temperature stamping preforming process, ensures the dimensional accuracy and the surface quality in the high temperature stamping final forming process, and can separate out tiny and uniform dispersed nano reinforced phases to improve the toughness. A large amount of dislocation can be generated in the ultra-low temperature stamping and high temperature stamping processes, and a favorable position can be provided for more fine nano strengthening phase precipitation in the subsequent pre-ageing and deep cooling treatment processes. High strength parts can be obtained without further ageing treatment.
The aluminum alloy prepared by the preparation method has obviously improved forming precision, strength, corrosion resistance and production efficiency.
In some embodiments of the present invention, in step S1, the heat preservation time is 10 to 30min.
Under the heat preservation time, the condition that the heat preservation time is too short, so that solute elements in the aluminum alloy do not have enough time to diffuse and precipitate, the strength, the hardness and the corrosion resistance of the material cannot reach the expected effect is avoided, the condition that the heat preservation time is too long, the solute elements in the aluminum alloy are excessively diffused and precipitated phases are coarsened, and the strength and the hardness of the material are reduced is avoided.
In some preferred embodiments of the present invention, the method of forming an aluminum alloy includes the steps of:
s1, cooling an aluminum alloy material to-130 ℃ to-170 ℃ at a cooling rate of 110-130 ℃/s, and then preserving heat, and stamping and preforming;
s2, heating the preformed aluminum alloy to 380-420 ℃ at a heating rate of 10-30 ℃/s, and cooling after final hot stamping;
s3, pre-aging the aluminum alloy cooled in the step S2, cooling to-130 ℃ at a cooling rate of 110-130 ℃/S, heating to 180-220 ℃ at a heating rate of 10-30 ℃/S, and preserving heat.
In some embodiments of the present invention, in step S1, the pressure maintaining time in the pressing step is 8-12S.
In some embodiments of the present invention, in step S2, the dwell time in the hot stamping step is 18 to 22S.
In some embodiments of the present invention, in step S2, the cooling rate of the cooling is 20 to 40 ℃/S.
In some embodiments of the present invention, the pre-ageing temperature is 140-200 ℃, and the pre-ageing time is 10-60 min.
In some embodiments of the present invention, the aluminum alloy material in step S1 includes a room temperature quenched aluminum alloy material.
In some embodiments of the invention, the aluminum alloy material includes one of a 2-series alloy, an aluminum lithium-series alloy, a 6-series alloy, and a 7-series alloy.
