  • Patent number: 10570490
    Abstract: A method of strengthening a dilute magnesium alloy sheet includes providing a dilute magnesium alloy sheet, which includes a magnesium alloy consisting essentially of (wt %): >0 to 3.0 of Zn; >0 to 1.5 of Ca; 0 to 1.0 of Zr; 0 to 1.3 of a rare earth element or mixture of the same; 0 to 0.3 of Sr; 0 to 0.7 of Al, the balance of Mg and other unavoidable impurities, wherein the total weight % of alloying elements is less than 3%; subjecting the dilute magnesium alloy sheet to plastic deformation, in which the tensile plastic strain should exceed 0.5%, but be less than 8% to form a pre-deformed magnesium alloy sheets; and subjecting the pre-deformed magnesium alloy sheets to an ageing treatment in a temperature range of 80 to 250° C. for at least 1 minute, thereby forming a strengthened magnesium alloy sheet.

  • Publication number: 20190299263
    Abstract: A high-efficient rolling process for magnesium alloy sheet. The process is a rolling process for rolling billets. Parameters of the rolling process are: the rolling speed of each rolling pass is 10˜50 m/min, the rolling reduction of each rolling pass is controlled to be 40˜90%, and both the preheating temperature before rolling and the rolling temperature of each rolling pass are 250˜450° C. A preparation method for magnesium alloy sheet. The method comprises the steps of: 1) preparing rolling billets; 2) high-efficient hot rolling: controlling the rolling speed of each rolling pass to be 10˜50 m/min, controlling the rolling reduction of each rolling pass to be 40˜90%, and controlling both the preheating temperature before rolling and the rolling temperature of the each rolling pass to be 250˜450° C.; and 3) performing annealing.
