| 摘要 |
A process for making high strengh, high ductility, low density aluminum-base alloys, consisting essentially of 2,5 to 5 wt % Li, 0,15 to 2 wt % Zr, 0 to 5 wt % of at least one element selected from the group consisting of Cu, Mg, Si, Se, Ti, U, Hf, Be, Cr, V, Mn, Fe, Co, Ni, balance Al. The alloy is given multiple aging treatments after being solutionized. The microstructure of the alloy is characterized by the precipitation of a composite phase in the aluminum matrix thereof. |
