摘要： There are provided a magnesium alloy coil stock having good flatness and a method for producing the magnesium alloy coil stock, and a magnesium alloy structural member that uses the coil stock and a method for producing the magnesium alloy structural member. The coil stock is obtained by coiling a sheet composed of a magnesium alloy in a cylindrical shape, and the internal diameter of the coil stock is 1000 mm or less. When a test piece 1 for warpage amount obtained by cutting the coil stock is paced on a horizontal table 100, the ratio of the maximum distance h in a vertical direction regarding a gap 110 between the test piece 1 and the horizontal table 100 relative to the width w of the test piece 1 is 0.5% or less. The coil stock can be produced by rolling a cast material obtained by subjecting a magnesium alloy to continuous casting, subjecting the rolled sheet to warm leveling, and coiling the worked sheet in a cylindrical shape while the temperature just before coiling is decreased to 100° C. or less. By sufficiently decreasing the temperature just before coiling, there is provided a coiled sheet with good flatness in which warpage in the width direction is not easily formed even if the number of turns is large and curling is not easily formed even if the coiling diameter is small.

摘要： The method of producing a magnesium alloy joined part has the following steps: a joining step of joining a reinforcing material made of metal to a plate material made of magnesium alloy without allowing an organic material to remain at the joined portion and a plastic-working step of performing plastic working on the plate material to which the reinforcing material is joined. A desirable means of joining the reinforcing material to the plate material can be to use an inorganic adhesive. Because the magnesium alloy joined part is formed by a structure in which the reinforcing material is joined to the plate material, in comparison with the case where the reinforcing material is formed by machining or the like, the magnesium alloy structural member can be obtained with high production efficiency.

摘要： A formed product of a magnesium alloy having excellent impact resistance and a magnesium alloy sheet suitable as a material for the formed product are provided. The formed product is produced by press-forming a magnesium alloy sheet having an Al content of 7% by mass to 12% by mass and has a flat portion that is not subjected to drawing deformation. In a metal texture in a cross section of the flat portion in the thickness direction, the number of coarse intermetallic compound (Mg17Al12) particles having a particle size of 5 μm or more present in a surface area region extending from a surface of the flat portion to a position one-third of the thickness from the surface in the thickness direction is five or less. The formed product has a texture in which the number of coarse precipitations d1 is small and in which fine precipitations d0 are dispersed. The formed product is less likely to be dented even when impacted because of dispersion strengthening owing to the fine precipitations and solid-solution strengthening owing to Al that sufficiently forms a solid solution.

摘要： A plurality of magnesium alloy parts are joined to one another through an inorganic joining layer (an reinforcing material 2, a boss 3, and a pin 4 are joined to a base material 1). Concrete examples of the inorganic joining layer include a layer of an inorganic adhesive and a metal thin film formed on the magnesium alloy part at the time of hot cladding. Because the magnesium alloy parts are joined together through the inorganic joining layer, in comparison with the case where a reinforcing material and the like are formed by machining, waste of the material can be reduced. The use of the inorganic joining layer can produce a magnesium alloy structural member that does not generate hazardous smoke and soot even when it is melted for recycling.

摘要： Provided are a rolled Mg alloy material which has a wide width and whose mechanical properties are uniform in a width direction, a Mg alloy structural member produced by plastically working the rolled Mg alloy material, and a method for producing the rolled Mg alloy material. The method for producing a rolled Mg alloy material includes rolling a Mg alloy material with a reduction roll. The Mg alloy material has a width of 1,000 mm or more, and the reduction roll has three or more regions in the width direction. The temperature is controlled in each of the regions so that a difference between a maximum temperature and a minimum temperature is 10° C. or less in the width direction of a surface of the reduction roll. The variation in the rolled state in the width direction can be reduced by reducing a difference in temperature over the width direction of the reduction roll. As a result, it is possible to produce a rolled Mg alloy material whose mechanical properties are substantially uniform in the width direction.

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.
