文摘Several Al-Cu-Fe-Mg powders were produced by rapid solidification.The powders are crystalline at room temperature,but start to be transformed into quasicrystals when being heated to 600℃ and almost transformed to single icosahedral phase quasicrystals at about 800℃,and then,transformed into crystalline materials again at about 900℃.In this paper,the phase structural changes during heating,the composition range and formation characteristic of the Al-Cu-Fe-Mg quasicrystals are reported.
