A new amorphous Al87.3Fe4.3V0.7Si1.7Mm6.0(Mm: misch metal) was prepared by using melt-spinning technique. Differential scanning calorimetry (DSC), X-ray diffraction (XRD). transmis-sion electron microscopy (TEM) and energy dispersive X-ray (EDX) have been used to investigatethe crystallization behaviour of thi5 amorphous alloy It is found that the crystallization processcan be concluded as follows: amorphous→ amorphous plus fcc-Al→ fcc-Al plus AI11(La,Ce)3plus i-phase (icosahedral)→ fcc-Al plus Al11(La,Ce)3 plus i-phase plus ic-phase (icosahedralcompounds). The results of microhardness measurement show that HV values are higher thanthose in Al-Fe-V-Si based alloy and the maximum HV value corresponds to the coexisting ofnanoscale Al particles and i-phase.
