摘　　要：本文研究了Al90 Fe5Ce5和A190 Ni5Ce5非晶合金及预峰在晶化过程和时效过程中的稳定性。Al90Fe5Ce5非晶合金的晶化开始温度TX 和时效稳定性比Al90 Ni5Ce5非晶合金高。Al90 Fe5Ce5非晶合金预峰所对应的化学短程序结构的稳定性较高 ,而Al90 Ni5Ce5非晶合金预峰所对应的化学短程序结构的稳定性差 ,甚至通过常温时效消失。The stability of amorphous Al 90 Fe\-5Ce\-5 and Al 90 Ni\-5Ce\-5 alloys and the prepeak during crystallization process and aging process were investigated.The crystallization onset temperature and stability during aging process for amorphous Al 90 Fe\-5Ce\-5 alloys is much higher than that of the amorphous Al 90 Ni\-5Ce\-5 alloys.The structure corresponding to the prepeak for amorphous Al 90 Fe\-5Ce\-5alloys is stable during first crystallization stage.However,it is not stable for amorphous Al 90 Ni\-5Ce\-5 alloys,even decomposes by aging at room temperature.The stability of the structure corresponding to the prepeak strongly correlates with the stability of the amorphous Al 90 TM\-5Ce\-5 alloys.
