Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A magnesium alloy material having high corrosion resistance is provided. The magnesium alloy material contains a magnesium alloy containing 7.3% to 16% by mass Al, wherein a region having an Al content of 0.8x % by mass or more and 1.2x % by mass or less occupies 50% by area or more, a region having an Al content of 1.4x % by mass or more occupies 17.5% by area or less, wherein x % by mass denotes the Al content of the entire magnesium alloy material, and there is substantially no region having an Al content of 4.2% by mass or less. The magnesium alloy material has small variations in Al concentration and includes a few regions having a very low Al content, thereby effectively preventing and retarding local corrosion. Thus, the magnesium alloy material has higher corrosion resistance than die-cast components having the same Al content.

Abstract: 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.

Abstract: A casting nozzle for supplying a molten alloy liquid of aluminum alloy or magnesium alloy to a movable mold for continuous casting from a tundish, in which the molten alloy liquid is stored. The casting nozzle is fixed to the tundish. The casting nozzle tip arranged on the movable mold side is made of a highly heat-conductive material having a heat conductivity of 0.2 W/mK or more, and a highly elastic material having an elastic modulus of 5000 MPa or more, etc. By making the tip of the casting nozzle with a material having superior thermal conductivity, the irregularity in solidification of the molten alloy liquid is decreased and thereby the surface quality of a cast alloy is improved. The nozzle tip is formed with a material having high elasticity and superior elastic deformability, whereby the interstice between the movable mold and the tip of outer peripheral edge of the nozzle is narrowed, and accordingly a cast alloy having superior surface quality can be obtained.
