抄録

Microstructures of aluminum containing lithium up to 9.75% solidified at various cooling rates from 10-1 to 3× 105°C/s were examined. The microstructures of these alloys are classified into three types in accordance with the cooling rate and lithium content; i) aluminum solid solution. ii) aluminum solid solution+precipitated Al3Li(δ')iii) eutectic Al3Li(δ). The precipitation of the metastable δ' during cooling is not suppressed. The lithium content that metastable δ' particles precipitate is independent on the cooling rate. The grain size of aluminum alloys corresponds to lithium content and cooling rate.
