    摘要： A method of producing a long magnesium material excellent in the plastic workability and a long magnesium material obtained according to the producing method are provided.Pure magnesium or a magnesium alloy is cast to prepare a cast material and, to the cast material, the plastic working is applied to prepare a long processed material. The plastic working includes a hot process that accompanies a cross sectional area reduction and is applied at a temperature of 250° C. or more. When the hot process is applied, during the process, in the vicinity of a surface of a workpiece, an oxide is generated and present there. The oxide, when the plastic working (secondary working) such as drawing and forging is applied to the formed material, may be a starting point of the crack or disconnection. In this connection, in the invention, a surface layer of the formed material is removed to effectively remove the oxide that becomes a starting point of the crack or disconnection, and thereby the secondary workability is improved.
