Title:
MAGNESIUM ALLOY ROLLED MATERIAL AND PRODUCTION METHOD THEREFOR, AND PRESS-FORMED ARTICLE
Document Type and Number:
Japanese Patent JP2017078220
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a magnesium alloy rolled material having high ductility at a recrystallization temperature or lower, a production method therefor and a press-formed article.SOLUTION: The magnesium alloy rolled material contains Al of 0.3 mass% or more and less than 3 mass%, a first group element of 0.1 mass% to 1.5 mass% and a second group element of 0.05 mass% to 1.5 mass% and the balance Mg with inevitable impurities and has an intensity ratio difference ΔR defined by ΔR=|Rc-Re|/(Rc+Re)/2 of 0.5 or less, where Rc is intensity ratio of an X-ray diffraction peak intensity derived from a (0002) plane to an X-ray diffraction peak intensity derived from a (10-10) plane at a center part of the magnesium alloy rolled material and Re is intensity ratio of the X-ray diffraction peak intensity derived from the (0002) plane to the X-ray diffraction peak intensity derived from the (10-10) plane at an edge part of the magnesium alloy rolled material.SELECTED DRAWING: None
