| Abstract Scope |
We developed methods for visualizing two types of concentration fields in material processing using fluorescence imaging. The first process involves imaging Ca2+ concentration and pH when the steel slag phases are in contact with aqueous solution. The increase in pH due to elution of alkaline components presents a challenge when slag is utilized outdoors. To elucidate the elution mechanism and provide insights for designing slag applications, a fluorescence imaging technique was established using fluorescence probes in the biological field. In the presentation, the imaging results of the elution process from CaSiO3 will be presented. The second process involves imaging the solute concentration distributions from microsegregation during steel solidification using a simulated transparent material. Visualization of solute enrichment between dendrite arms and the formation of inclusions, both caused by microsegregation, will be discussed. Both fluorescence imaging methods visualize microscale phenomena near the solid-liquid interface, offering new insights into their mechanisms. |
