Title:
MAGNESIUM ALLOY AND METHOD FOR MANUFACTURING MAGNESIUM ALLOY PLATE
Document Type and Number:
Japanese Patent JP2010242149
Kind Code:
A
Abstract:

To provide a high strength alloy casting plate which is practical and excellent in soundness by preventing generation of defects like black stripes of a casting plate.

The magnesium alloy consists of, by mass, 2-10% Al, 0.1-0.5% Mn, ≥0.004 to <0.03% C, ≤1.2% Zn (including 0%), and the balance substantially Mg with inevitable impurities. In the magnesium alloy, many of Al4C3are formed in a temperature region higher than those of crystal grains of magnesium in solidification, Al4C3functions as a crystal core, and thus, aluminum crystal grains are equalized and miniaturized.
