通过快凝试验和电镜观察，对Ａｌ－Ｆｅ－Ｖ－Ｓｉ合金中块状相的产生条件进行了分析．结果表明，合金中块状相产生的温度范围为１１７３－１１０３Ｋ，当熔体在该温度区间的冷却速度临界冷却速度，而快凝开始后的时形成块状相加微胞晶的快凝缺陷组织，当在整个快凝过程中时，则形成块状相加粗胞晶的快凝缺陷组织．

The icosahedral quasicrvstalline phase (i-phase) with the chemical composition of 82.4at%Al. 8.8at%Fe. 3.6at%V and 5.2at%Si in melt spun Al-Fe-V-Si ribbons was found. It is suggested that the temperature and holding time of the melt prior to quenching are the important factors in the formation of the i-phase.
