Document Type and Number:
WIPO Patent Application WO/2023/080056
Kind Code:
A1
Abstract:
[Problem] To provide a Mg-based alloy extension material with which it is possible to reduce yield anisotropy while maintaining excellent tensile yield strength properties. [Solution] Provided is an Mg-based alloy extension material having excellent room-temperature strength and containing Mn and at least one element from among the four elements Al, Ca, Li, and Zn, or further containing, in addition to the above four elements, the two elements Sn and/ Bi, with the remainder made up by Mg and unavoidable impurities, wherein the Mn content is 0.03–2 mol% (inclusive), and the content of the aforementioned six elements is at least 0.03 mol% but no greater than the Mn content. The extension material is characterized in that the yield stress obtained by a tensile test is 200 MPa or above and exhibits a ratio, relative to the yield stress obtained by a compressive test, of 0.6 or above.
