Title:

MANUFACTURE OF ROLLED PRODUCT OF MAGNESIUM ALLOY, METHOD OF PRESS WORKING MAGNESIUM ALLOY, AND PRESS WORKED PRODUCT

Document Type and Number:

Japanese Patent JP3523500

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a method of manufacturing a rolled product of magnesium alloy having excellent cold workability, a method of press working the magnesium alloy, and a press worked product.
SOLUTION: This is a method for manufacturing a rolled product of magnesium alloy having a composition containing 6 to 10.5 wt.% lithium and also having an eutectic structure consisting of a magnesium alpha phase 1 and a lithium beta phase 2. This method comprises a cold rolling stage where the magnesium alloy is cold rolled at least at ≥10% draft to desired thickness and a stage where, after the cold rolling stage, heat treatment is applied at 150 to 300°C for 10 min to 2 hr to recrystallize the magnesium alpha phase.
