Grain refining effects of carbon (C2Cl6) addition were investigated using
AZ31 magnesium alloy. The addition of C2Cl6 to AZ31 magnesium alloy
significantly reduced the grain size from 400㎛to about 120㎛. The tensile
properties were increased due to grain refinement. EPMA analysis
showed that apparent segregation of carbon element was occurred in
AZ31castings treated with carbon. It was considered that the carbon may
have strong segregating power that restrict the grain growth and affect the
constitutional undercooling which, in turn, results in grain refining effects.
