将纳米级尖端阵列与组合薄膜沉积和处理以及直接原子级表征（APT和TEM）相结合，可以加速探索多元材料系统中依赖于温度和环境的相演变。纳米晶CrMnFeCoNi的结果表明，这种合金不稳定，在约300摄氏度的低温下1小时后就已经分解。组合处理平台方法可扩展到在原子尺度上探索复杂结构和功能材料中的氧化和腐蚀。
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 degrees C. The combinatorial processing platform approach is extendible to explore oxidation and corrosion in complex structural and functional materials on the atomic scale.
