Phase Formation and Stability in Icosahedral Phase Metallic Alloys

这项研究的目的是为了更好地了解与二十面体相的形成和稳定性相关的潜在机制。研究了与二十面体结构形成有关的几个因素，包括溶质原子尺寸、电子数和电负性的影响。研究了钛-锰-硅体系中稳定二十面体相的结晶，以确定其行为随硅浓度的变化。正在计划对选定的二十面体相体系进行扩散散射行为和结晶研究。

This research is aimed at greater understanding of the underlying mechanisms associated with the formation and stability of icosahedral phases. Several factors associated with the development of icosahedral structure are under examination, including effects of solute atom size, electron count and electronegativity. The crystallization of stable icosahedral phases in the titanium-manganese-silicon system is being examined to determine how the behavior changes with silicon concentration. Diffuse scattering behavior and crystallization studies are being planned for selected icosahedral phase systems.
