Abstract: The magnesium ingots from factory A, B and C were remelted. The microstructure and property of un-remelted and remelted magnesium ingots were investigated. The results indicate that the microstructure and property of the remelted magnesium alloy take on a hereditary transmission similar or resembling to those of feed materials. The characteristics of the short range order structure atomic group in alloy is the same as or resembles to that of feed materials during the melting process. The hereditary transmission of magnesium alloy can be explained by atomic conglobation theory.
Key words: AZ91D magnesium alloy; hereditary transmission; remelting
