研究了钛硅二元合金熔体急冷非晶相的形成、稳定性和分解特性。电子显微镜和衍射结合X射线衍射技术表明，非晶相可以在含15至20原子%的硅的合金中获得。非晶相向平衡相的转变分两个阶段进行。一个亚稳的B C C钛固溶体，含有超过平衡值的硅，最初形成，随后由Ti5Si3金属间化合物的沉淀。在分解的各个阶段的微观结构特征已被描述和解释的合金的构成。研究了非晶合金的力学性能。
The formation, stability and decomposition characteristics of the amorphous phase in binary titanium-silicon alloys rapidly quenched from the molten state have been investigated. Electron microscopy and diffraction coupled with X-ray diffraction techniques suggested that the amorphous phase could be obtained in alloys containing 15 to 20 at% silicon. The transformation of the amorphous phase to the equilibrium phases took place in two stages. A metastable b c c titanium solid solution, containing silicon in excess of the equilibrium value, formed initially, followed by the precipitation of the Ti5Si3 intermetallic compound. Microstructural features at various stages of decomposition have been described and interpreted in terms of the constitution of the alloys. Mechanical properties of the amorphous alloys have also been investigated.
