摘要： The invention offers a pressed product (F) produced by press-forming a metal plate (1). The pressed product (F) has a peripheral surface that has a corner portion (12) connecting two surfaces in the peripheral surface. The corner portion (12) has an outside corner radius R that is equal to or smaller than the thickness “t” of the metal plate (1). That is, the pressed product (F) has the sharp corner portion (12).

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%.
