Title:
マグネシウム合金材及びその製造方法
Document Type and Number:
Japanese Patent JP5757104
Kind Code:
B2
Abstract:
There are provided a magnesium alloy material and a method for producing the magnesium alloy material. In a magnesium (Mg) alloy material having a sheet-shaped portion with a thickness of 1.5 mm or more, when a region having ¼ the thickness of the sheet-shaped portion in a thickness direction from a surface of the sheet-shaped portion is defined as a surface region and a remaining region is defined as an internal region, the ratio OF/OC of the basal plane peak ratio OF in the surface region to the basal plane peak ratio OC (degree of orientation of (002) planes) in the internal region satisfies 0.95@OF/OC@1.05. A sheet-shaped Mg alloy material is obtained by performing at least one pass of the rolling at a reduction ratio of 25% or more and the remaining passes of the rolling at a reduction ratio of 10% or more.
