文摘

An immiscible Al-Co-La-Pb alloy with an amorphous phase was designed. Ultra-fine Pb globules, dispersed in Al-based amorphous alloys, were successfully obtained. Multistep liquid-phase separation occurred in Al-Pb–based immiscible alloys. STEM clarified the particle structures in Pb-enriched and oxide globules
