Title:
Zn-Al ALLOY HAVING EXCELLENT HIGH-SPEED DEFORMATION PROPERTIES AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/129355
Kind Code:
A1
Abstract:
This invention provides a Zn-Al alloy, which is excellent in static deformability, as well as in dynamic deformability, and can be applied to a large structure, and a process useful for producing the Zn-Al alloy. The Zn-Al alloy comprises Zn: 30 to 99% (% by mass; the same shall apply hereinafter) with the balance consisting of Al and unavoidable impurities, wherein the Zn-Al alloy has a texture comprising a β phase finely dispersed in an &agr phase or &agr ’ phase having an average grain diameter of not more than 5 µm, the maximum diameter of Al-based inclusions is not more than 50 μm, and, at the same time, pores having a equivalent circle diameter of not less than 0.5 mm are absent, and the macrosegregation of Al is less than 3.0%, and the microsegregation of Al is less than 2.0%.
