Combining nanoscale-tip arrays with combinatorial thin film deposition and processing as well as direct atomic-scale characterization (APT and TEM) enables accelerated exploration of the temperature- and environment-dependent phase evolution in multinary materials systems. Results from nanocrystalline CrMnFeCoNi show that this alloy is unstable and already decomposes after 1 h at low temperatures of around 300 °C. The combinatorial processing platform approach is extendible to explore oxidation and corrosion in complex structural and functional materials on the atomic scale.

组成成分复杂的材料中原子演化的原子级加速探索

将纳米级尖端阵列与组合的薄膜沉积和处理技术以及直接的原子级表征(APT和TEM)相结合,可以加速探索多元材料系统中与温度和环境有关的相演化。CrMnFeCoNi纳米晶体的结果表明,该合金不稳定,在300°C左右的低温下1 h后便已分解。组合处理平台方法可扩展到以原子尺度探索复杂结构和功能材料中的氧化和腐蚀。
