【摘要】 本文对室温下100keV Ar离子束注入到Ti-Al和Fe-Al两个二元系中几种成分的样品进行了研究。透射电镜、背散射分析和表面电阻测量被用于对多层膜离子束混合过程的分析。研究结果表明:Ti-Al二元系中能在很宽的成分范围内形成非晶相,而Fe-Al二元系中只有成分为Fe₂₅Al₇₅附近的样品中才观察到非晶相的形成。对这两个系统中的结果,本文进行了初步的讨论。更多还原

【Abstract】 A study of ion mixing of the multilayered samples with various alloy composition in binary metal systems of Ti-Al and Fe-Al was carried out by means of the transmission electron microscope, Rutherford backscattering analysis and the sheet electrical resistivity measurement. The experimental results showed that the Ti-Al amorphous phases had been formed in wide alloy composition range by 100 keV Ar ion mixing, while the Fe-Al amorphous phase had been formed only in an alloy composition around Fe25Al75 under similar conditions. The experimental results are discussed in connection with the current predictions.更多还原
