Abstract

The effect of irradiation on the atomic structure of a Cu50Ti50 metallic glass is investigated by X-ray diffraction. The irradiation is seen to produce significant changes in the structure factor S(Q)of this glass, and the changes observed are quite opposite to those caused by low-temperature annealing. Changes are also observed in the reduced radial distribution function G(r). All these changes are finally discussed in conjunction with the topological short range ordering (TSRO) and chemical short range ordering (CSRO) of the metallic glass. Bestrahlungseffekte infolge Rontgenbeugung auf die atomare Struktur von metallischen Cu50Ti50-Glas werden untersucht. Die Bestrahlung ruft signifikante Anderungen des Strukturfaktors S(Q) dieses Glases hervor und die beobachteten Anderungen stehen im volligen Gegensatz zu denen der Niedertemperaturausheilung. Anderungen werden auch fur die reduzierte radiale Verteilungsfunktion G(r) beobachtet. Alle diese Anderungen werden im Zusammenhang mit der topologischen Nahordnung (TSRO) und der chemischen Nahordnung (CSRO) der Metallglaser diskutiert.

快中子辐照对Cu50Ti50金属玻璃结构影响的研究
《原子结构中的伊朗行为》清洗者在这玻璃中制造了严重的结构变化,观察这些变化造成了赵国人遭受轻微的偏见。还包含着不断加深的归化效应G(r)。所有这些改变在与金属玻璃的高温热水和化学厂达成的共识中最终破灭了。由于rontse对cu50ti50玻璃的核结构进行辐照作用。化疗的叫重大Anderungen Strukturfaktors S (Q)这一出来,而且你的主观的观察Anderungen一直处于什么不像他们,Niedertemperaturausheilung .同时也观察到缩小的放射性分布函数G(r)。所有这些Anderungen与topologischen Nahordnung (TSRO)和化学Nahordnung——CSRO Metallglaser .讨论
