Abstract
The present invention relates to a magnesium aluminum alloy with enhanced creep resistance. The alloy contains barium and calcium in low proportions, and possesses a higher creep resistance in comparison to alloys containing rare earth elements. The alloy may additionally include zinc, tin, lithium, manganese, yttrium, neodymium, cerium and/or praseodymium in proportions of up to 7% by weight, respectively.
Description
Technical field
The present invention relates to creep resistance Dow metal.
Background technology
The metal alloy that contains magnesium is widely used in motor vehicle industry, electron trade, aerospace industry and some other technical fields.These alloys are especially favourable, and they have high temperature creep-resisting, therefore can be used for hot environment.
Several different magnesium alloy have been developed and with its stdn, for example magnesium alloy JIS H5203 (MC1-MC10) and JIS H 5303 (MDC1A, MDC1B).The alloy A that consists of Mg-4%Al-2%RE (RE is a rare earth metal) of DOW Chemical (DowChemical) company exploitation is used for high-temperature use as everyone knows.
Yet this class heat resistance magnesium alloy is unsuitable for casting very much, wherein metal object cooling rapidly after being shaped.
DE 44 46 898 A1 disclose creep resistance Dow metal, and described magnesium alloy comprises: the aluminium of 1.5 to 10 weight % (Al), the rare earth element (RE) that is less than 2 weight %, the calcium (Ca) of 0.25 to 5.5 weight % and the magnesium of surplus.In addition, this alloy can comprise copper and/or the zinc of 0.2 to 2.5 weight %.
Yet the rare earth element that comprises in this class alloy has increased the cost of alloy.
DE 22 01 460 A1 also disclose creep resistance Dow metal, and this magnesium alloy comprises aluminium and optional other element that is selected from calcium, zirconium, titanium, silicon, strontium, yttrium, cerium or barium.The combination of unexposed barium and calcium is as other element.
Summary of the invention
Therefore, an object of the present invention is to provide above-mentioned shortcoming that can overcome prior art and magnesium alloy with higher creep resistance.
This purpose realizes by magniferous metal alloy or magnesium alloy, based on the gross weight of alloy, described magniferous metal alloy or magnesium alloy contain the aluminium (Al) of 1 to 9 weight %, the barium (Ba) of 0.5 to 5 weight %, the calcium (Ga) of 0.5 to 5 weight %, the magnesium (Mg) and inevitably relevant with the production impurity of surplus.Preferably, 2 weight % of the described inevitably relevant no more than alloy gross weight of total impurities with production.The ratio of aluminium is preferably 2 to 7 weight %, more preferably 3 to 6 weight %.The ratio of barium is preferably 1 to 4 weight %, more preferably 1.5 to 3 weight %.The ratio of calcium is preferably 1 to 4 weight %, more preferably 1.5 to 3 weight %.
Magnesium alloy of the present invention also can comprise ratio in addition and be respectively zinc, tin, lithium, manganese, yttrium, neodymium, cerium and/or the praseodymium of 7 weight % at the most.
Magnesium alloy of the present invention can be used for a plurality of Application Areass; Be preferred for producing the parts of motor vehicle, ship and/or flyer, more preferably be used to produce power-driven gear and parts thereof.
Description of drawings
Fig. 1 be explanation when applying 80MPa stress and under 200 ℃ of temperature, the figure as the creep strain of the function of time of conventional alloy A E42, two kinds of magnesium alloy of the present invention (ABC alloy) and the MRI230D alloy produced by Dead Sea Magnesium company.
Embodiment
Invention will be further ex-plained with reference to the appended drawings.In Fig. 1, shown respectively when applying 80MPa stress and under 200 ℃ of temperature, the alloy of the commodity MRI230D by name that produces with conventional alloy A E 42 (wherein E represents rare earth element) with by Dead Sea Magnesium company (also containing rare earth element except aluminium and calcium) is compared, the creep strain as the function of time of two kinds of magnesium alloy of the present invention (ABC alloy), described two kinds of magnesium alloy (ABC alloy) contain the aluminium of the 4 weight % that have an appointment respectively, the aluminium of the calcium of the barium of about 2 weight % and about 1 weight % (ABC421) and about 4 weight %, the calcium of the barium of about 2 weight % and about 2 weight % (ABC422).
Alloy of the present invention has the creep strain that significantly is lower than comparative alloy separately.This draws as drawing a conclusion: under constant stress, and temperature even can further raise, perhaps parts can stand obvious longer time of stress.
