Title:
MAGNESIUM ALLOY MATERIAL AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/069049
Kind Code:
A1
Abstract:
Disclosed is a magnesium alloy material which can be produced without the need of
employing any specialized production facility or process and has excellent mechanical
properties, particularly high elongation. Also disclosed is a process for
producing the magnesium alloy material. The magnesium alloy material comprises
a Mg-Gd-Zn alloy comprising 1 to 5 mass% of Zn and 5 to 15 mass% of Gd as essential
ingredients, with the remainder being Mg and unavoidable impurities, wherein
the Mg-Gd-Zn alloy has a long period stacking structure in its alloy structure and
also has Mg3Gd and/or Mg3Zn3Gd2. The
process for producing the magnesium alloy material comprises a melting/casting step
and a forging processing step for subjecting the casted material to a hot forging
processing at a predetermined processing rate.
