MAGNESIUM ALLOY FOR HIGH TEMPERATURE AND A MANUFACTURING METHOD THEREOF TO INCREASE THE YIELD STRENGTH AND TENSILE STRENGTH OF MAGNESIUM ALLOY IN HIGH TEMPERATURE

摘要

PURPOSE: A magnesium alloy for high temperature and a manufacturing method thereof are provided to reduce casting defects and hold down the forming of thermally unstable β- Mg(Magnesium)17Al(Aluminum)12 phase.;CONSTITUTION: A manufacturing method of magnesium alloy for high temperature is as follows. Magnesium or magnesium alloy is dissolved into liquid. CaO(Calcium Oxide) is added to the surface of molten metal in which magnesium or magnesium alloy is dissolved. The desired quantity of Ca is generated in the Magnesium or magnesium alloy.;COPYRIGHT KIPO 2012
