    摘要: A method for manufacturing a magnesium alloy material includes the steps of: preparing a sheet or block of starting material that is made of a magnesium alloy; subjecting the starting material to a plastic working process at a temperature of 250°C or less and a reduction ratio of 70% or more to introduce strain without causing dynamic recrystallization; pulverizing the material subjected to said plastic working process into powder; compressively deforming said powder by passing said powder between a pair of rotating rolls; and successively crushing the compressively deformed powder, which has passed between the pair of rotating rolls, into granular powder.
