  • 초록

    Two approaches were made for improving the toughness of Al-Cu-Fe quasi-crystals(QC), i.e., addition of Sn to the Al-Cu-Fe QC(Al-Cu-Fe-Sn), and composite fabrication of Al-Cu-Fe quasi-crystals with various content of pure aluminium. Powders of quasi-crystals were made by atomizer. They were sintered as a disk by PAS (Plasma Activated Sintering) process which show some particular advantages during sintering. Composites of pure aluminium and Al-Cu-Fe quasi-crystal are also fabricated by PAS. The PASintered samples were examined by various methods. The experimental results represents that both the sintered specimens of Al-Cu-Fe-Sn QC and the composites have shown considerable improvement in toughness comparing with Al-Cu-Fe quasi-crystals(QC), if not applicable right away.
