Abstract (en)
[origin: EP1347074A1] In order to achieve the manufacture of products, which have complex and accurate figure and exhibit high reliability of properties and enough corrosion resistance, at sufficiently high yield ratio by employing a combination of casting and forging for forming magnesium alloy of which composition allows casting and which is excellent in forgeability, a magnesium alloy containing 2-10 mass % aluminum is cast to have crystal grain size not greater than 30 mu m. After the cast semifinished product is subjected to solution treatment, the semifinished product is forged to have crystal grain size not greater than 10 mu m and is then further forged to have a desired figure. A magnesium alloy containing 2-10 mass % aluminum is cast to have crystal grain size not greater than 10 mu m and the cast semifinished product is forged after solution treatment. <IMAGE>
