20090263268 | Raw Magnesium Alloy Powder Material, Magnesium Alloy with High Proof Stress, Manufacturing Method of Raw Magnesium Alloy Powder Material and Manufacturing Method of Magnesium Alloy with High Proof Stress - A raw magnesium alloy powder material having a relatively small crystal grain diameter is obtained by subjecting a starting material powder having a relatively large crystal grain diameter to a plastic working in which the powder is passed through a pair of rolls to undergo compressive deformation or shear deformation. The starting material powder is a magnesium alloy powder having a fine intermetallic compound ( | 10-22-2009 |
