| Abstract Scope |
Characterizing segregation in steel and alloys is essential, as it significantly influences the material's microstructure, mechanical properties, and overall performance. Effective characterization requires both high sensitivity to detect subtle variations in elemental concentration and high throughput to analyse large areas efficiently. Traditionally, techniques such as Electron Probe Microanalysis (EPMA) and Synchrotron Micro X-ray Fluorescence (SMXRF) have been employed for this purpose. However, these methods have notable limitations, including challenges in sample beam damage, spatial resolution, high costs, and lengthy acquisition times. In this talk, we introduce a new approach that combines a novel scanning electron microscopy technique, known as Backscattered Electron and X-ray (BEX), with energy-dispersive X-ray spectrometry (EDS). This innovative method allows for the high throughput characterization of segregation from nanoscale (<100nm) to macroscale (>cm), with the capability to map concentrations differences as low as 0.1 wt%. |
