Tuesday publication post! 📖 High-entropy silicides (HESs) are emerging as next-generation materials for microelectronics and mechanical applications. In this study, the #FusionAX system was used to reveal the silicidation dynamics of a novel HES, (CrFeCoNi)Si, synthesized via solid-state reaction.
What was observed?
🔥 Real-time diffusion tracking: Ni initiates silicidation at 400 °C, forming Ni₂Si.
📈 Phase evolution: Binary silicides (FeSi₂, Co₂Si) emerge at 500 °C, followed by ternary silicides (FeNiSi, CoNiSi) at 600 °C.
💠 Final transformation: CrSi₂ reacts at 700 °C to form the orthorhombic HES phase.
By performing in situ microscopy, it was possible to observe the diffusion-driven transformation pathways of high-entropy silicides, offering a new strategy for designing advanced functional materials.
