Description

Lengthened magnesium alloy
Technical field
The relevant lengthened magnesium alloy of the present invention, as be used to push, alloy material that processing is elongated in calendering etc., and process the building structural materials that makes by elongating with this alloy material.
Background technology
Here so-called " elongating processing " is meant that required shape is processed in process extruding, pressurization, forgings etc. such as forged material to extrusion molding material, rolled material, press molding material.
The lengthened magnesium alloy that is used for building structural materials was used as the M1 of the JIS of aluminum-zinc alloy in the past always.This M1 contains the aluminium of 3.0 weight % and the zinc of 1.0 weight %.
But the above-mentioned lengthened magnesium alloy of using till today is when extrusion processing, if forming speed is very fast, then molding can produce fracture, so just can not be shaped.And oxidation takes place in the molding surface, and surface properties is worsened, and can not be shaped.
On the other hand, the forming speed during the magnesium alloy rolling processing wishes to improve.
The content of invention
According to above-mentioned situation, the objective of the invention is to provide lengthened magnesium alloy, it can with than in the past faster forming speed carry out extrusion processing, as structured material, it has sufficient mechanical property and corrosion resistance nature.
For reaching this purpose, feature of the present invention is, below the above 1.0 weight % of aluminium content 0.1 weight %, below the above 2.0 weight % of zinc content 0.1 weight %, below the above 1.0 weight % of manganese content 0.1 weight %, below the copper content 0.04 weight %, below the silicone content 0.05 weight %, below the iron level 0.005 weight %, below the nickel content 0.005 weight %.
During with lengthened magnesium alloy blank extrusion molding of the present invention, both made extrusion speed be about original 10 times, extrusion molded article does not rupture yet, and can be not on fire and can not be shaped owing to surface oxidation.Therefore, can with than originally faster extrusion speed come extrusion molding to make the Structure of magnesium alloy material.
With the physical properties of the extrusion molding goods of lengthened magnesium alloy of the present invention, as tensile strength, proof stress, elongation, corrosion resistance nature is all than in the past goods excellence, as the mechanical property of light material especially than in the past goods excellence.
Aluminium content is because during the discontented 0.1 weight % of aluminium content below the 1.0 weight % more than 0.1 weight %, can not obtain sufficient mechanical property as structured material, and when surpassing 1.0 weight %, is difficult to again obtain than extrusion speed faster in the past.
Zinc content is because during the discontented 0.1 weight % of zinc content below the 2.0 weight % more than 0.1 weight %, and corrosion-resistant, and when surpassing 2.0 weight % is difficult to again obtain than extrusion speed faster in the past.
Manganese content is because the erosion resistance the best in this scope below 1.0 weight % more than the 0.1 weight %.Manganese content is lower than 0.1 weight %, and the obvious variation of erosion resistance, and when surpassing 1.0 weight % is difficult to again obtain than extrusion speed faster in the past.
Lengthened magnesium alloy of the present invention preferably contains below the above 0.8 weight % of aluminium 0.2 weight %, below the above 1.0 weight % of zinc 0.2 weight %, manganese 0.3 weight %, below the above 0.04 weight % of copper 0.02 weight %, below the above 0.03 weight % of silicon 0.02 weight %, iron 0.004 weight %, below the nickel 0.001 weight %, all the other are magnesium.
According to experimental result, in these content ranges, not only extrusion speed is than in the past fast about 10 times, and mechanical propertiess such as the tensile strength of extrusion molded article are also than in the past excellence.
Copper, silicon.Iron, nickel all are the unavoidable impurities elements.
Also can add calcium to improve flame retardant resistance.The calcium addition is advisable with 0.3~1.0 weight %.
The content of rare earth elements such as yttrium, neodymium, cerium all when 100ppm is following, can improve high-temperature mechanical property by weight.

As shown in Table 2, in embodiment 1~3, extrusion speed (finished product speed) is respectively 5~50 meters/timesharing, can both extrusion molding, and the deterioration of surface properties does not take place in the outward appearance range estimation.Especially among the embodiment 1, under 70 meters/minute speed, surface properties does not worsen yet, can also extrusion molding.With respect to this, in the comparative example 1~3, speed is 10 meters/timesharing, though can the extrusion molding surface properties worsen, and under the speed more than 15 meters/minute, fracture takes place can not extrusion molding.That is, the extrusion speed of embodiment 1~3 comparative example 1~3 more than 10 times the time still can extrusion molding.
In the shape material extruding of as shown in Figure 2 section form, shown in the embodiment 1 of table 3, be that 20 meters/timesharing can also extrusion molding, but in comparative example 1, be that 5 meters/timesharing is just ruptured, can not extrusion molding.By the result of table 2 and table 3 as can be known, the section form difference of extruding shape material, extrusion speed is also different, but when same section form, the extrusion speed of embodiments of the invention is faster more than 10 times than comparative example.
The tensile strength of each embodiment and comparative example gained shape material as shown in Table 4, in the comparative example 1~3, extrusion speed one is fast, and tensile strength just obviously reduces, and the situation of present embodiment is, the similar energy the when tensile strength when extrusion speed is fast is slow with extrusion speed is identical.Especially be 10 meters/timesharing at extrusion speed, any tensile strength good than comparative example 1~3 all of embodiment 1~3.General typical tensile strength of elongating with aluminium alloy A6063 (JIS) is 220MPa, and the tensile strength of present embodiment is better than this elongation aluminium alloy.
In embodiment 1~3, also measured 0.2% elasticity polarity stress and elongation.0.2% elasticity polarity stress is 110~130MPa, and elongation is 8~12%, and the corrosion decrement of carrying out with 5%NaCl salt solution after 24 hours the spray testing is 2mg/cm 2/ day, with this evaluation criteria as erosion resistance.These physical propertiess are elongated almost or omit with aluminium alloy 6063 (JIS) with general, can be used as the lightweight structural material use.
Among the embodiment 1~3, also respectively with the blank manufacturing extruding shape material that has further added 0.3~1.0 weight % calcium, can extrusion molding under the speed identical with the foregoing description 1~3, mechanical property is also identical simultaneously, compare with the above-mentioned shape material that does not add calcium, because surface oxidation and incidence on fire reduces to some extent is so improved flame retardant resistance.
Among the embodiment 1~3, also respectively with further having added the blank manufacturing extruding shape material of rare earth elements such as the yttrium below 100ppm, neodymium, cerium by weight, can extrusion molding under the speed identical with the foregoing description 1~3, and the mechanical property under the high temperature (200-300 ℃) is better than the foregoing description.
Lengthened magnesium alloy of the present invention is not limited to be used on the extrusion molding, also can be used for calendering, press molding, forging, and these fabricated products can obtain the effect same with the extrusion molding goods.
As mentioned above, utilize the present invention, can with than in the past faster extrusion speed magnesium alloy is carried out extrusion molding processing.And the surface properties that can not occur causing because of the fracture of extrusion molding goods or surface oxidation are on fire etc. worsens.
