    摘要： The invention offers a magnesium alloy sheet material having excellent plastic processibility and rigidity and a magnesium alloy formed body having excellent rigidity. The sheet material has magnesium alloy that forms the matrix containing hard particles. The region from the surface of the sheet material to a position away from the surface by 40% of the thickness of the sheet material is defined as the surface region, and the remaining region as the center region. Hard particles existing in the center region have a maximum diameter of more than 20 μm and less than 50 μm, and hard particles existing in the surface region have a maximum diameter of 20 μm or less. Because the hard particles existing at the surface side are fine particles, they are less likely to become the starting point of cracking or another defect at the time of plastic processing. Because the hard particles existing in the center region are coarse, they can increase the rigidity of the sheet material.

    摘要： The invention offers a magnesium alloy sheet having excellent warm plastic formability, a production method thereof, and a formed body produced by performing warm plastic forming on this sheet. The magnesium alloy sheet is produced by giving a predetermined strain to a rolled sheet RS that is not subjected to a heat treatment aiming at recrystallization. The sheet is not subjected to the foregoing heat treatment even after the giving of a strain. The strain is given through the process described below. A rolled sheet RS is heated in a heating furnace 10. The heated rolled sheet RS is passed between rollers 21 to give bending to the rolled sheet RS. The giving of a strain is performed such that the strain-given sheet has a half peak width of 0.20 deg or more and 0.59 deg or less in a (0004) diffraction peak in monochromatic X-ray diffraction. The alloy sheet exhibits high plastic deformability by forming continuous recrystallization during warm plastic forming through the use of the remaining strain.

Regarding the method for manufacturing a coil material through coiling of a sheet material formed from a metal into the shape of a cylinder, so as to produce the coil material, the sheet material is a cast material of a magnesium alloy discharged from a continuous casting machine and the thickness t (mm) thereof is 7 mm or less. The sheet material 1 is coiled with a coiler while the temperature T (° C.) of the sheet material 1 just before coiling is controlled to be a temperature at which the surface strain ((t/R)×100) represented by the thickness t and the bending radius R (mm) of the sheet material 1 becomes less than or equal to the elongation at room temperature of the sheet material 1.

    摘要： There is provided a lightweight, high strength impact-resistant component having a good impact energy absorptive property. The impact-resistant component is composed of a magnesium alloy containing Al in an amount of more than 7.3% by mass and 12% or less by mass. A rectangular test piece is produced from the impact-resistant component; an iron ball 30 having a mass of 225 g is allowed to freely fall toward a central portion of the test piece while both end portions of the test piece are fixed to supports 21 and 22; and, when a distance between a position from which the iron ball 30 is allowed to freely fall and the test piece is assumed to be a fall height, a fall height H at which a dent is not generated on the test piece by the iron ball 30 is measured. The impact-resistant component has a fall height H of more than 340 mm. In the impact-resistant component of the present invention, the fall height at which a dent is not generated is large. Therefore, the impact-resistant component of the present invention is not dented or is not easily dented even if an impact is applied and thus has high impact resistance.

    摘要： There is provided a composite structural member having high rigidity even at a small thickness, the composite structural member being easily attachable to a target object. A composite structural member 1A includes a metal base material 10A, a resin formed article 11, and a resin film layer 12 that covers a surface of the metal base material 10A. The metal base material 10A is a plastically formed material formed by subjecting a flat sheet material having a thickness of 50 μm or more to press forming. The metal base material 10A and the resin film layer 12 are joined together using a constituent resin of the resin formed article 11. The composite structural member 1A includes the metal base material 10A and thus can have excellent strength and rigidity even at a smaller thickness. The composite structural member 1A includes the resin formed article 11. An attaching portion to the target object can be easily formed in the resin formed article 11. Thus, the composite structural member 1A has excellent mounting workability. The composite structural member 1A includes the resin film layer 12 and thus has excellent design properties.
