Abstract (en)

[origin: WO2007054152A1] A process for casting a magnesium alloy consisting of 2,0 - 6,00 % by weight of aluminium, 3,00 - 8,00 % by weight of rare earth metals (RE-metals), the ratio of the amount of RE-metals to the amount of aluminium expressed as % by weight being larger than 0,8, at least 40 % by weight of the RE-metals being cerium, less than 0,5 % by weight of manganese, less than 1,00 % by weight of zinc, less than 0,01 % by weight of calcium less than 0,01 % by weight of strontium and the balance being magnesium and unavoidable impurities, the total impurity level being below 0,1 % by weight, wherein the alloy is cast in a die the temperature of which is controlled in the range of 180-340°C, the die is filled in a time which expressed in milliseconds is equal to the product of a number between 5 and 500 multiplied by the average part thickness expressed in millimeter, the static metal pressures being maintained during casting between 20-70 MPa and is subsequently intensified up to 180 MPa.
