摘要 利用 X 射线衍射、扫描电子显微镜和电子探针微量分析等实验技术,在 1270 K 下测定了三元 RE-Si-B 图中的固态相平衡(RE = Dy、Ho、Er 和 Y)。通常,每个图都获得了三个三元相:具有四方对称性的线状化合物 RE 5 Si 2 B 8、Mn 5 Si 3 型的硼插入 Nowotny 相 RE 5 Si 3 B x 和固溶体 REB 2 - x Si x 的AlB 2 -型。在这项工作之前,还重新研究了构成每个图边界的二元系统 RE-Si 和 RE-B。除了先前报道或将在即将发表的报告中介绍的 RE 5 Si 3 (Mn 5 Si 3 型,RE = Dy、Ho 和 Y)和 Dy 3 Si 4(Ho 3 Si 4 型)的结构之外纸,RE 5 Si 4(Sm 5 Ge 4 型,RE = Dy 和 Ho)、DySi(CrB 型)和 HoSi 的 X 射线单晶结构在两种多晶型变体中,即
Reactions between Si and thin films of rare‐earth metals (Gd, Dy, Ho, Er, plus Y and La) in the temperature range of 275–900 °C have been studied by using x‐ray diffraction and ion backscattering spectrometry. The disilicides of these metals are apparently the first phase to form, forming rapidly within a narrow temperature range (325–400 °C), and are stable up to 900 °C. The growth does not follow
已经使用 X 射线衍射和离子背散射光谱法研究了 Si 与稀土金属(Gd、Dy、Ho、Er、加上 Y 和 La)薄膜在 275-900°C 温度范围内的反应。这些金属的二硅化物显然是第一个形成的相,在狭窄的温度范围 (325–400 °C) 内迅速形成,并在高达 900 °C 时保持稳定。增长不遵循分层增长模式。

Phase equilibria in the Dy–Ti–Si system at 1200 K

Phase equilibria in the Dy-Ti-Si system were investigated by X-ray powder diffraction, local X-ray spectral analysis, metallographic analysis and the isothermal cross-section at 1200 K was obtained. The CeFeSi-type (space group P4/nmm, No. 129) DyTiSi compound has been confirmed. The new Sc2Re3Si4-type (space group P4(t)2(t)2, No. 92) compound Dy2Ti3Si4 [a=0.6977(l) nm, c=1.2814(2) nm] was found. It is obvious that the AlB2-type (space group P6/mmm, No. 191) compound DyTi0.3Si1.7 [a=0.3824(1) nm, c=0.4119(1) nm] belongs to an extended region of the AlB2-type DySi1.56-based solid solution.

Phase equilibria in the Dy-V-Si system were investigated by X-ray powder diffraction and metallographic analysis. The isothermal cross-section at 1200 K was obtained. It is obvious that the AlB2-type (space group P6/mmm, no. 191) DyV0.1Si1.9 compound [a=0.3817(1) nm, c=0.4114(1) nm] belongs to the extended region of an AlB2-type DySi1.56-based solid solution.
