MAGNESIUM ALLOY WITH HEAT RESISTANCE AND FLAME RETARDANCY, AND METHOD OF MANUFACTURING THE SAME

Japanese Patent JP2013019030

A

To provide a magnesium alloy with heat resistance and flame retardancy usable under a high temperature environment, and a method of manufacturing the same.

The magnesium alloy 10 contains 0.5-5 mass% Ca and 0.5-5 mass% Si, and a CaMgSi phase 12 is crystallized in a Mg phase 11 serving as a parent phase, thereby providing the heat resistance. The method of manufacturing the magnesium alloy 10 includes the steps of: heating a Mg alloy raw material in a molten state sequentially added with Ca and Si in a temperature range of 800-900°C and then solidifying the same; and crystallizing the CaMgSi phase 12 in the Mg phase 11 serving as the parent phase, thereby providing the heat resistance.
