二元非晶态合金结构模型化的R_t判据
A NEW CRITERION OF CONSTRUCTING THE STRUCTURAL MODEL OF BINARY AMORPHOUS ALLOYS
【摘要】 类金属原子的相对分布是过渡金属-类金属(TM-M)型非晶态合金结构中化学短程序的一个重要特征。本文根据这一思想定义了一个新的制作此类非晶态合金结构模型的判据,并使用此判据制作了几个组分和成分都各不相同的结构模型,分别模拟Ni64B36,Fe80B20,Ni31B19和Co81P19非晶态合金的结构。所得的各部分径向分布函数Gij(r)都与实验相符。将这些结果与前人的工作作了比较,并进行了讨论。
【Abstract】 The relative distribution of the metalloid atoms is one of the most important characteristic of the chemical short-range order in the structure of the amorphous alloys consist of metal-metalloid. Basing on this idea, a new criterion of constructing the structural model of this kind of alloys is proposed, and several models are made by a computer with this new criterion, which simulate the structures of amorphous alloy Ni64B36,Fe80B20,Ni81B19 and Co81P19 respectively. All of the partial distribution functions of these models are in agreement with the experiments. These results are also compared with other author’s works and discussed.
