TY - JOUR A1 - Straub, Franka A1 - Wirth, Thomas A1 - Hertwig, Andreas A1 - Hodoroaba, Vasile-Dan A1 - Unger, Wolfgang A1 - Böllinghaus, Thomas T1 - Imaging the microstructure of duplex stainless steel samples with TOF-SIMS N2 - Time-of-flight secondary ion mass spectrometry (TOF-SIMS) mappings provide a visualization of the distribution of chemical elements and phases on polished duplex steel surfaces as element and fragment secondary ion signals. The advantage of TOF-SIMS, compared to optical microscopy, is its potential to analyze the chemical composition with a lateral resolution at a submicrometer scale. TOF-SIMS mappings allow distinguishing between ferritic and austenitic phases because of the phase selective detection method without any requirement of etching or other processing.
