Description
Australian Patents Act 1990 - Regulation 3.2 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title Creep-resistant magnesium alloy The following statement is a full description of this invention, including the best method of performing it known to me/us: P/00/0 li S102 - la The present invention relates to a creep-resistant magnesium alloy. Metal alloys containing magnesium are used extensively in the automotive industry, electronic industry, aerospace industry and several other technical areas. Those alloys are especially advantageous, which are high temperature creep-resistant and therefore usable in a high temperature environment. Several different magnesium alloys have been developed and standardized, such as the magnesium alloys JIS H 5203 (MC1 MC10) and JIS H 5303 (MDC1A, MDClB). Alloy A having the composition Mg-4%Al-2%RE (RE = rare earth elements) , which has been developed by the company Dow Chemical, is also well known for high temperature use. However, such heat-resistant magnesium alloys are quite inapplicable in casting, 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 weight of aluminum (Al) , less than 2 % by weight of rare earth elements (RE), 0.25 to 5.5 % by weight of calcium (Ca), the balance being magnesium. In addition, the alloy may contain 0.2 to 2.5 % by weight of copper and/or zinc. The rare earth elements contained in such alloys, however, increase the costs of the alloy. DE 22 01 460 Al also discloses creep-resistant magnesium alloys containing aluminum and optionally an additional element selected from calcium, zirconium, titanium, silicon, -2 strontium, yttrium, cerium or barium. Barium and calcium in combination are not disclosed as additional elements. It is therefore the object of the present invention to provide a magnesium alloy, which is able to overcome the above mentioned disadvantages of the state of the art and, moreover, has a higher creep resistance. The object is solved by a metal alloy containing magnesium or magnesium alloy, containing 1 to 9 % by weight of aluminum (Al), 0.5 to 5 % by weight of barium (Ba), 0.5 to 5 %- by weight of calcium (Ca) , the balance being magnesium (Mg) and inevitable production-related impurities, based on the total weight of the alloy. Preferably, the inevitable production related impurities amount in total to no more than 2 % by weight, based on the total weight of the alloy. 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 weight. The proportion of calcium is preferably 1 to 4 % by weight, more preferably 1.5 to 3 % by weight. 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 weight, respectively. The magnesium alloy of the invention may be used in a multiplicity of application areas; 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. The invention is further illustrated with reference to the attached figure. In figure 1, the creep deformation as a -3 function of time with an applied strain of 80 MPa and a temperature of 2000C of two inventive magnesium alloys (ABC alloys) containing about 4 % by weight of aluminum, about 2 % by weight of barium and about 1 % by weight of calcium (ABC421) and about 4 % by weight of aluminum, about 2 % by weight barium and about 2 % by weight of calcium (ABC422), respectively, is shown in 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 rare earth elements in addition to aluminum and calcium. The inventive alloys have a considerably lower creep deforma tion than the respective 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 times. Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.
