Two‐layer In–Pb films with a thickness from 50 to 200 nm, which are obtained by the method of sequential vacuum condensation, are used to study the phase diagram in this binary system. In–Pb films with a smooth composition change (0–100%) and annealing temperature (20–400 °C) are obtained within a single experimental cycle. The original method of variable composition and variable state is used. With this method of obtaining, the boundaries are observed on the substrate separating different regions of the film. X‐ray diffraction studies show that these areas correspond to different phase states of the sample and visualize the phase diagram of a binary system. The In–Pb phase diagram observed in the films generally corresponds to that for bulk samples. With an increase in the annealing temperature, the dispergation of the films intensifies. Below the liquidus temperature, the films consist of inhomogeneous in composition particles of irregular shape. Above the liquidus line, the films consist of homogeneous islands in the form of a spherical segment. Their size distribution is unimodal with a maximum; the position of which in a wide range does not depend on the concentration of the components.

In-Pb合金在凝聚膜中的相图
通过连续真空冷凝法获得的厚度为50至200 nm的两层In-Pb薄膜用于研究该二元系统中的相图。在单个实验周期内即可获得具有平稳成分变化（0-100％）和退火温度（20-400°C）的In-Pb薄膜。使用原始的可变组成和可变状态方法。使用这种获得方法，在分隔膜的不同区域的基板上观察到边界。X射线衍射研究表明，这些区域对应于样品的不同相态，并且可以直观地看到二元系统的相图。薄膜中观察到的In–Pb相图通常对应于大量样品的相图。随着退火温度的升高，膜的分散增强。在液相线温度以下，膜由不规则形状的不均匀组成颗粒组成。在液相线上方，薄膜由球形段形式的均匀岛组成。它们的大小分布是单峰的，最大。其位置在宽范围内不取决于组分的浓度。
