Abstract
A method of manufacturing products, which have complex and accurate shape and exhibit high reliability of properties and enough corrosion resistance, at sufficiently high yield 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 shape. 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.
