비정질 Ti50Be40Zr10 합금의 구조분석 = The Structure Analysis of an Amorphous Ti50Be40Zr10 Alloy

다국어 초록 (Multilingual Abstract)

Using AgKα radiation (λ=0.5608Å) in transmission, the structure of a melt-spun amorphous Ti_(50)Be_(40)Zr_(10) alloy has been determined.
The amorphous alloys, especially the metal-metalloid alloys, are known to possess similar structures, each with a relatively strong first peak in I(K) and a shoulder on the high K-side of a broad second peak. Though not a metal-metalloid alloy, the Ti_(50)Be_(40)Zr_(10) alloy shows such a typical structure as those for metal-metalloid alloys. However, the first peak in I(K) of this alloy, appearing at K₁= 2.754Å^(-1) looks a little more diffuse than those of the metal-metalloid alloys. In addition, the maximum of the shoulder on the second peak in I(K) occurs below 1.
The interatomic distance for the first nearest neighbors is estimated from the position r₁ of the first peak in g(r) as 2.920Å. Also the number of the first nearest neighbors, i.e., the coordination number, is estimated from the area under the first peak in the radial distribution function as 15.1.
