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.
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
Agent Ref: 71404/00005 4 The present invention relates to a creep-resistant magnesium alloy.
7 Metal alloys containing magnesium are used extensively in the automotive industry, 8 electronic industry, aerospace industry and several other technical areas.
Those alloys are 9 especially advantageous, which are high temperature creep-resistant and therefore usable in a high temperature environment.
12 Several different magnesium alloys have been developed and standardized, such as the 13 magnesium alloys JIS H 5203 (MC1-MC10) and JIS H 5303 (MDC1A, MDC1B). Alloy A having 14 the composition Mg-4%AI-2%RE (RE = rare earth elements), which has been developed by the company Dow Chemical, is also well known for high temperature use.
17 However, such heat-resistant magnesium alloys are quite inapplicable in casting, 18 wherein the metal object must be cooled rapidly after shaping.
DE 44 46 898 Al discloses creep-resistant magnesium alloys, containing: 1.5 to 10 % by 21 weight of aluminum (Al), less than 2 % by weight of rare earth elements (RE), 0.25 to 5.5 % by 22 weight of calcium (Ca), the balance being magnesium. In addition, the alloy may contain 0.2 to 23 2.5 % by weight of copper and/or zinc.
The rare earth elements contained in such alloys, however, increase the costs of the 26 alloy.
28 DE 22 01 460 Al also discloses creep-resistant magnesium alloys containing aluminum 29 and optionally an additional element selected from calcium, zirconium, titanium, silicon, strontium, yttrium, cerium or barium. Barium and calcium in combination are not disclosed as 31 additional elements.
21912040.1 Agent Ref: 71404/00005 2 It is therefore the object of the present invention to provide a magnesium alloy, which is 3 able to overcome the above mentioned disadvantages of the state of the art and, moreover, has 4 a higher creep resistance.
6 In one aspect, the invention provides a magnesium alloy, containing the following 7 ingredients, based on total weight of the alloy: 1 to 9 % by weight of aluminum; 0.5 to 5 % by 8 weight of barium; 0.5 to 5 % by weight of calcium; and with the balance being magnesium.
BRIEF DESCRIPTION OF THE FIGURE
11 Figure 1 illustrates creep deformation as a function of time.
14 The object is solved by a metal alloy containing magnesium or magnesium alloy, containing 1 to 9 % by weight of aluminum (AI), 0.5 to 5 % by weight of barium (Ba), 0.5 to 5 %
16 by weight of calcium (Ca), the balance being magnesium (Mg) and inevitable production-related 17 impurities, based on the total weight of the alloy. Preferably, the inevitable production-related 18 impurities amount in total to no more than 2 % by weight, based on the total weight of the alloy.
19 The proportion of aluminum is preferably 2 to 7 % by weight, more preferably 3 to 6 % by weight. The proportion of barium is preferably 1 to 4 % by weight, more preferably 1.5 to 3 % by 21 weight. The proportion of calcium is preferably 1 to 4 % by weight, more preferably 1.5 to 3 %
22 by weight.
24 The magnesium alloy of the invention may additionally include zinc, tin, lithium, manganese, yttrium, neodymium, cerium and/or praseodymium in proportions of up to 7 % by 26 weight, respectively.
28 The magnesium alloy of the invention may be used in a multiplicity of application areas;
29 preferably it is used in the production of components for automotives, vessels and/or aeroplanes, more preferably in the production of power trains and components thereof.
32 The invention is further illustrated with reference to the attached figure.
In figure 1, the 33 creep deformation as a function of time with an applied strain of 80 MPa and a temperature of 34 200 C of two inventive magnesium alloys (referred to as "ABC alloys", or aluminum, barium and 21912040.1 2 Agent Ref: 71404/00005 1 calcium alloys) containing about 4 % by weight of aluminum, about 2 % by weight of barium and 2 about 1 % by weight of calcium ("ABC421 ") and about 4 % by weight of aluminum, about 2 % by 3 weight barium and about 2 % by weight of calcium ("ABC422"), respectively, is shown in 4 comparison to a conventional alloy AE42, wherein E denotes rare earth elements, and an alloy produced by the company Dead Sea Magnesium under the name of MRI230D, which contains 6 rare earth elements in addition to aluminum and calcium.
8 The inventive alloys have a considerably lower creep deformation than the respective 9 comparison alloys. This leads to the conclusion that, with constant strain, the temperature may be increased even further, or that a component may be strained for considerably prolonged 11 times.
13 Although the invention has been described with reference to certain specific 14 embodiments, various modifications thereof will be apparent to those skilled in the art without departing from the purpose and scope of the invention as outlined in the claims appended 16 hereto. Any examples provided herein are included solely for the purpose of illustrating the 17 invention and are not intended to limit the invention in any way. Any drawings provided herein 18 are solely for the purpose of illustrating various aspects of the invention and are not intended to 19 limit the invention in any way.
