摘　　要：研究了Cu基二元块体非晶合金的形成能力,解释了多元合金的非晶形成能力。通过比较已有的二元铜基块体非晶合金的试验数据发现,在内能差相差不大的情况下,混合熵差对于非晶形成能力有着重要的影响。Glass forming ability （GFA） of Cu based binary bulk amorphous alloy was analyzed, and GFA of the multi-element amorphous alloy was expounded. Through analyzing comparatively the experimen- tal data of Cu-base binary amorphous alloy, the results reveal that in the condition of slight difference between internal and external energy, mixed entropy difference between liquid and crystals plays a key role in GFA of the amorphous alloy.

关 键 词：二元Cu基块体非晶合金 热力学 非晶形成能力
