| Outline of Final Research Achievements |
Development of the foundry of the Al-Li alloy of high quality, the measurement of the formability of a made alloy and application for die-casting were investigated. The rolling workability of the Al-1～4mass%Liand Al-2mass%Mg-1mass%Li alloy produced by “Tilt-casting method” were excellent. On the other hand, increasing of solute elements of Cu ,Mg and Li was decrasing in rolling-formability due to remained of δ(AlLi) crystallized phase in the structure in those alloys.
