Magnesium base alloy wire |
摘要 |
Magnesium-based alloy wire excelling in strength and toughness, its method of manufacture, and springs in which the magnesium-based alloy wire is utilized are rendered. <??>The magnesium-based alloy wire contains, in mass %, 0.1 to 12.0% Al, and 0.1 to 1.0% Mn, and is provided with the following constitution. <??>Diameter d that is 0.1 mm or more and 10.0 mm or less; length L that is 1000d or more; tensile strength that is 250 MPa or more; necking-down rate that is 15% or more; and elongation that is 6% or more. <??>Such wire is produced by draw-forming it at a working temperature of 50 DEG C or more, and by heating it to a temperature of 100 DEG C or more and 300 DEG C or less after the drawing process has been performed. <IMAGE> |
