Title:
MAGNESIUM ALLOY PLATE, PRESS COMPACT, AND METHOD FOR MANUFACTURING MAGNESIUM ALLOY PLATE
Document Type and Number:
WIPO Patent Application WO/2021/214890
Kind Code:
A1
Abstract:
This magnesium alloy plate is formed from a magnesium-base alloy. The magnesium base alloy has: a composition comprising at least 2.0% by mass and less than 4.5% by mass of aluminum; and a structure. The structure is configured so that fb/fa is at least 10, mL/mC and mL/mD are at least 0.9 and less than 1.3, and the maximum value of the relative intensity of the basal crystal orientation is 5.2 or less, when: crystal orientation is measured by the EBSD; the proportion of the number of pixels in which the basal crystal orientation is inclined at an angle of 0°–10° from a plate surface to all pixels in one visual field is fa; the proportion of pixels for which the crystal orientation is inclined at an angle of 25°–45° from the plate surface is fb; the Schmid factor of basal slip when a direction orthogonal to both a plate width direction and a plate thickness direction is the tensile direction is mL; the Schmid factor of basal slip when the plate width direction is the tensile direction is mC; and the Schmid factor of basal slip when a direction inclined by 45° is the tensile direction is mD.
