A NEW CRITERION OF CONSTRUCTING THE STRUCTURAL MODEL OF BINARY AMORPHOUS ALLOYS

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 Ni 64 B 36 ,Fe 80 B 20 ,Ni 81 B 19 and Co 81 P 19 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.
