摘要： Provided are a magnesium alloy sheet having excellent formability in plastic forming, such as press forming, and a magnesium alloy structural member. The magnesium alloy sheet is obtained by subjecting a magnesium alloy to rolling and has a cross section parallel to the thickness direction of the magnesium alloy sheet, in which, when the length of the major axis and the length of the minor axis of each of crystal grains in the cross section are determined, an aspect ratio is defined as the ratio of the length of the major axis to the length of the minor axis (length of major axis/length of minor axis), and crystal grains having an aspect ratio of 3.85 or more are defined as elongated grains, the area fraction of the elongated grains in the cross section is 3% to 20%.

摘要： A composite member includes a metal sheet having a bent portion formed by bending, and a resin member joined to at least a part of the bent portion. The metal sheet includes an opening provided on an inner side of the bent portion, and a tapered recess that tapers off from an outer side of the bent portion toward the opening. The resin member includes an inner resin part filled in the recess, and an exposed resin part provided to be continuous with the inner resin part and to extend to an inner surface of the bent portion through an edge portion of the opening.

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： 本发明提供一种具有优异的耐热塑性成形性的镁合金板及其制造方法，以及通过在该片上进行热塑性成形而制成的成形体。 通过对未进行再结晶的热处理的轧制板RS给予规定的应变来制造镁合金板。 即使施加了应变，片材也不进行上述的热处理。 通过下述方法给出菌株。 轧制板RS在加热炉10中被加热。加热的轧制板RS在辊21之间通过，以使轧制板RS弯曲。 进行应变的施加使得在单色X射线衍射中的（0004）衍射峰中，应变给定片的半峰宽度为0.20度以上且0.59度以下。 通过使用剩余的应变，通过在热塑性成型期间形成连续的再结晶，合金板表现出高的塑性变形性。
