SUPERPLASTIC ALUMINIUM ALLOY PRODUCTS AND METHOD OF PREPARATION |
摘要 |
Aluminum alloy products having superplastic properties are prepared by casting an aluminum alloy containing calcium and zinc in near-eutectic proportions under conditions that develop a eutectic cast structure of fine Ca-Zn-Al intermetallic rods, and working the cast alloy mass to break up the rods into particles having an average diameter of less than two microns. |
