Description

A kind of space flight and aviation ZK61M magnesium alloy
Technical field
The invention belongs to alloy manufacturing technology fields, and in particular to a kind of space flight and aviation ZK61M magnesium alloy.
Background technique
Magnesium alloy is the smallest metal of specific gravity in light metal, this material is particularly suitable for applications in space flight and aviation.But because ZK61M materials hot working temperature range is relatively narrow, only 50 degree or so, is difficult to complete hot rolling within this range, therefore lead to not Plate is produced, domestic at present also without any standard about plate, only production forging (only forge at present by ZK61M magnesium alloy Part standard), but the performance of forging standard is not able to satisfy the material property of space flight and aviation application.ZK61M forging standard and space flight boat Sky standard is as shown in table 1.
Note: H112 is natural cooling state in table, is national forging standard (country is without ZK61M plates specifications), parantheses in parantheses It is the mechanical property of aerospace plate requirement outside.
Current any magnesium alloy materials mechanical property does not have three-dimensional requirement, and strip requires longitudinal performance;It squeezes and requires longitudinal direction Performance;Forging requires longitudinal and transverse two performances.However whatsoever standard, material do not require high Xiang Xingneng, but space flight and aviation The three-dimensional performance of material is required with plate, and every to all beyond standard regulation.The high tropism energy tensile strength of ZK61M is extremely difficult to 220N/mm2, it is specified that disproportional strength is extremely difficult to 120N/mm2;For this reason, it may be necessary to a kind of novel ZK61M magnesium alloy is researched and developed, To realize the material property of space flight and aviation application, industry blank is filled up.
Summary of the invention
The object of the invention is that providing a kind of space flight and aviation ZK61M magnesium conjunction to solve the deficiencies in the prior art Gold.
The purpose of the present invention is what is realized with following technical proposals:
A kind of space flight and aviation ZK61M magnesium alloy, it is through the following steps that be prepared:
(1) it forges: the ZK61M circle ingot casting for meeting YS/T 627-2013 deformed Mg and magnesium alloy circle ingot casting standard is heated Forging, heating temperature are 420-430 DEG C, and heating time 13-16 hour carries out when forging in length, width, highly three directions Forging, final forging temperature be not less than 350 DEG C, obtain forging plate;
(2) hot rolling: then the forging plate that step (1) is obtained carries out steering rolling, is rolled in 400-420 DEG C of heating 6-9h Then making sheet A carries out the rolling of small working modulus multi-pass at 345-355 DEG C of temperature, finally obtaining total plus power is 26-27%'s Hot rolled plate;
(3) timeliness: the hot rolled plate that step (2) is obtained carries out 170-180 DEG C of ageing treatment 22-26h, obtains space flight and aviation use ZK61M magnesium alloy.
The forging ratio that three step (1) length, width, height directions are all made of 10-20 is forged.
Step (1) ZK61M circle ingot diameters are Φ 300-500mm, length 600-700mm, are finally forged to The circle ingot casting that length is 600-700mm is first forged and pressed to 300-400mm when forging, then again will by the forging plate of 150-155mm thickness The flat forging and stamping of circle forging and stamping are rectangle, then are forged in three length, width, height directions.
It is 22-23% that the step (2), which turns to the milled sheet A working modulus obtained after rolling, and it is more then to carry out small working modulus again The rolling of passage finally obtains the hot rolled plate that total plus power is 26-27%.
The step (2) turns to rolling concrete operations are as follows: is first thickness 137- by the forging plate axial rolling of 150-155mm thickness The plate of 141mm then turns to the plate that transverse rolling is thickness 126-130mm, turns again to the plate that axial rolling is thickness 119-123mm, finally Turn to transverse rolling be thickness 114-116mm milled sheet A, then carry out the rolling of small working modulus multi-pass, roll for a thickness of The milled sheet of 109-112mm.
Passage number is not less than 6-8 passage in the rolling of the small working modulus multi-pass.
The present invention is first by the ZK61M circle ingot casting for meeting YS/T 627-2013 deformed Mg and magnesium alloy circle ingot casting standard first First to be forged, the blank interior tissue after forging becomes worked structure from cast sturcture, and hot-working relatively easily rolls, Also, in order to meet final material performance, when forging, will carry out three directions forging and stamping, and it is more that small-power is then finally carried out when hot rolling The rolling of passage, it is ensured that three-dimensional performance, finally by ageing treatment, the magnesium alloy three-dimensional performance produced exceeds aviation boat Needed for its material, good it can be applied to space flight and aviation military industry.
Specific embodiment
