摘要： A magnesium alloy structural member having excellent corrosion resistance is provided. The magnesium alloy structural member includes a magnesium alloy substrate that contains more than 7.5% by mass ofAl and an anticorrosive layer formed on a surface of the substrate by chemical conversion treatment. The substrate contains a precipitate, typically, particles dispersed therein. The particles are made of an intermetallic compound containing at least one of Al and Mg and have an average particle size of 0.05 µm or more and 1 µm or less. The total area of the particles accounts for 1% by area or more and 20% by area or less. The anticorrosive layer includes a lower sublayer and a surface sublayer on the substrate in this order. The surface sublayer is denser than the lower sublayer. The substrate of the magnesium alloy structural member has high corrosion resistance because of a high Al content. The magnesium alloy structural member has excellent corrosion resistance because of the dense sublayer on the front side of the anticorrosive layer, which prevents a corrosive liquid from reaching the substrate. The porous lower sublayer can reduce the tendency of the anticorrosive layer to detach from the substrate, for example, upon impact and allows the magnesium alloy structural member to retain high corrosion resistance.

摘要： There is provided a magnesium alloy member having mechanical properties and corrosion resistance and a method of manufacturing the magnesium alloy member. A magnesium alloy member has a base material made of a magnesium alloy, and an anticorrosive film formed on the base material. The base material is a rolled magnesium alloy including 5 to 11% by mass of Al. By using a base material including a large amount of Al, a magnesium alloy member having excellent mechanical properties and high corrosion resistance can be produced. In addition, by using a rolled material, the number of surface defects at the time of casting is small, and the frequency of compensation processes such as undercoating and puttying can be reduced:

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.

摘要翻译： 提供具有优异耐腐蚀性的镁合金结构部件。 所述镁合金结构部件包括含有超过7.5质量％的Al的镁合金基材和通过化学转化处理形成在所述基材表面上的防腐蚀层。 基材含有沉淀物，典型地，其中分散有颗粒。 粒子由含有Al和Mg中的至少一种的金属间化合物构成，平均粒径为0.05μm以上且1μm以下。 颗粒的总面积占1面积％以上，20面积％以下。 防腐蚀层依次包括在基材上的下部子层和表面子层。 表面子层比下层子层更致密。 由于Al含量高，所以镁合金结构部件的基材具有高耐腐蚀性。 镁合金结构部件由于在防腐蚀层的前侧上具有致密的子层而具有优异的耐腐蚀性，这防止了腐蚀性液体到达基底。 多孔下部子层例如可以降低防腐蚀层从基材上剥离的倾向，例如在冲击时，并允许镁合金结构部件保持高耐腐蚀性。
