Abstract
The present invention relates to a kind of aluminium alloy Technology for Heating Processing, including following operating procedure: the first step: collect timeliness mistake, but underproof product；Second step: the alloy product of timeliness is heated to 210 230 DEG C, is incubated 6 10min；3rd step: be rapidly cooled to room temperature；4th step: again alloy product is carried out timeliness heating according to new technology.The present invention is by a kind of new Technology for Heating Processing, the alloy product of timeliness is heated through between low-temperature short-time, state after making it substantially return to solid solution, then Ageing Treatment is re-started, due to without solution treatment, therefore the number of times done over again for heat treatment is not strict with, and reprocesses for substandard product and serves very important effect.
Description
Technical field
The present invention relates to technical field of heat treatment technology, especially a kind of aluminium alloy Technology for Heating Processing.
Background technology
Aluminium alloy is little due to density, specific strength and specific modulus advantages of higher, becomes the application of current aerospace field non-
A kind of material, owing to aluminium alloy is to heat treatment temperature sensitive, adjusts solid solution and aging temp can be to mechanical property
Can produce considerable influence, for requiring stricter product, technology controlling and process is the most improper, may result in aberrations in property and causes power
Performance is defective, causes product to be done over again, and alloy product has strict demand to number of times of doing over again, it is impossible to repeat heat treatment more than 2
Secondary, therefore can only scrap through the underproof product of repeatedly heat treatment.
Existing aluminum alloy ring forging is defective due to mechanical property, and the treating method done over again is only solid solution aging again,
Alloy product has very strict requirement to solid solution number of times, because repeating heat treatment the mechanical property of product can be caused one
Fixed loss.If being still unable to reach requirement through repeating the alloy product performance of solid solution, it will cause scrapping.Aluminium alloy
Owing to value of the product is of a relatively high, scrap and can cause the biggest loss.The present invention by by underproof for performance product through too low
Temperature short time heating so that it is come back to solid solution condition, then by adjusting heat aging technique, re-starts the timeliness of product.
The repeatedly heat treatment that can be realized defective work by the present invention is done over again, and heat time heating time is short simultaneously, heating-up temperature is low, and operation is more
Simply.
Summary of the invention
The applicant is for the shortcoming in above-mentioned existing production technology, it is provided that a kind of aluminium alloy Technology for Heating Processing, thus real
The repeatedly heat treatment of existing aluminium alloy defective work is done over again, is reprocessed, and reduces the scrappage of product.
The technical solution adopted in the present invention is as follows:
A kind of aluminium alloy Technology for Heating Processing, including following operating procedure:
The first step: collect timeliness mistake, but underproof product；
Second step: the alloy product of timeliness is heated to 210-230 DEG C, is incubated 6-10min；
3rd step: be rapidly cooled to room temperature；
4th step: again alloy product is carried out timeliness heating according to new technology.
Its further technical scheme is:
In described 4th step, new technology is: alloy product is heated to 160-163 DEG C, is incubated 6-7h.
Beneficial effects of the present invention is as follows:
The alloy product of timeliness, by a kind of new Technology for Heating Processing, is heated through between low-temperature short-time by the present invention,
State after making it substantially return to solid solution, then re-starts Ageing Treatment, due to without solution treatment, therefore for heat
Process the number of times done over again not to be strict with, substandard product is reprocessed and serves very important effect.
The present invention is after overaging, and the hardening constituent composition of aluminium alloy is generally GP district and θ " phase, the dissolving temperature of both phases
Spend relatively low, respectively less than 200 DEG C, be therefore heated to 210-230 DEG C, GP district and θ " dissolving of phase almost all, hardening constituent all dissolves
After, alloy will return to the state after solid solution, under this state, can re-start timeliness according to new technique.With existing aluminum
Alloy heat treatment technique of doing over again compares, it is possible to achieve repeatedly doing over again, heat time heating time is short simultaneously, heating-up temperature is low, and operation is more
Simply.
Detailed description of the invention
The detailed description of the invention of the present invention is described below.
The aluminium alloy Technology for Heating Processing of the present embodiment, including following operating procedure:
The first step: collect timeliness mistake, but underproof product；
Second step: the alloy product of timeliness is heated to 210-230 DEG C, is incubated 6-10min；
3rd step: be rapidly cooled to room temperature；
4th step: again alloy product is carried out timeliness heating according to new technology.
In 4th step, new technology is: alloy product is heated to 160-163 DEG C, is incubated 6-7h.
In actual mechanical process, being such as originally that timeliness 165 DEG C is incubated 7h, present new technology uses and is incubated 7h with 160 DEG C,
Can also be 165 DEG C of insulation 6h.Depending on practical situation, aging temp and temperature retention time are all to reduce than original technique.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees right
Requirement, within protection scope of the present invention, can make any type of amendment.
