摘要：

DSC data from melt-spun ribbons of two Al-Ni-Y-Co-Fe alloys have revealed three distinct stages in the devitrification. TEM studies show that these stages correspond to the formation of fee alpha-Al,Al-9(Ni,Co,Fe)(2), and a mixture of Al-19(Ni,Co,Fe)(5)Y-3+Al-23 (Ni,Co,Fe)(6)Y-4, respectively.
