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 magnesium alloy sheet having good press formability, a magnesium alloy structural member produced by pressing the sheet, and a method for producing a magnesium alloy sheet are provided. The magnesium alloy sheet is composed of a magnesium alloy containing Al and Mn. When a region from a surface of the alloy sheet to 30% of the thickness of the alloy sheet in a thickness direction of the magnesium alloy sheet is defined as a surface region and when a 200 μm2 sub-region is arbitrarily selected from this surface region, the number precipitated impurity grains containing both Al and Mg and having a maximum diameter of 0.5 to 5 μm is 5 or less. When a 50 μm2 subregion is arbitrarily selected from the surface region, the number of crystallized impurity grains containing both Al and Mn and having a maximum diameter of 0.1 to 1 μm is 15 or less. In the grains of the crystallized phases, the mass ratio Al/Mn of Al to Mn is 2 to 5. The magnesium alloy sheet has good press formability since the crystallized phases and precipitates that cause breaking are small in amounts contained and in size.

摘要： A magnesium alloy sheet having high impact resistance at low temperature, a magnesium alloy structural member using this sheet, and a method for producing a magnesium alloy sheet are provided. The magnesium alloy sheet is composed of a magnesium alloy containing Al and Mn. When a region from a surface of the alloy sheet to 30% of the thickness of the alloy sheet in a thickness direction of the magnesium alloy sheet is defined as a surface region and when a 50 μm2 sub-region is arbitrarily selected from this surface region, the number of grains that are crystallized phases containing both Al and Mn is 15 or less. The maximum diameter of each of the crystallized phases is 0.1 to 1 μm and the mass ratio Al/Mn of Al to Mn is 2 to 5. This magnesium alloy sheet has high impact resistance since it contains crystallized phases that are small in size and in amount contained and cause breaking and the like, and exhibits good mechanical properties even in a low-temperature environment.

摘要： Provided are a rolled Mg alloy material whose mechanical properties are locally different 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 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 exceeds 10° C. in the width direction of a surface of the reduction roll. The rolled state in the width direction is varied by varying 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 locally different in the width direction.

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： 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.
