- Abstract:
- This study investigates the effectiveness of combining portable analytical techniques - Energy Dispersive X-ray Fluorescence (EDXRF) and Laser-Induced Breakdown Spectroscopy (LIBS) - as alternatives to traditional Spark Optical Emission Spectroscopy (Spark-OES) for the rapid assessment of key alloying elements Carbon (C), Silicon (Si), Manganese (Mn), Phosphorous (P) and Sulfur (S) in deformed steel bars. Both EDXRF and LIBS demonstrated strong accuracy and precision in analyzing C, Si, and Mn, with statistical analysis revealing significant correlations with the Spark-OES benchmark. However, detection of P and S requires further optimization due to inherent analytical challenges. The combination of these portable methods offers substantial advantages, including on-site testing capabilities and minimal sample preparation, enabling real-time monitoring and immediate quality control. The findings underscore the potential of EDXRF and LIBS to enhance quality assurance processes in the steel industry, promoting safer construction practices through efficient, non-destructive testing methods.
