| Abstract Scope |
High-temperature environments pose significant challenges for studying material degradation, particularly in capturing thermal transport behavior and microstructural evolution under simultaneous irradiation and heating. We present an advanced in-situ characterization platform designed to address these challenges. The system combines localized laser heating, infrared thermography, and numerical modeling to extract spatially resolved thermal conductivity and emissivity in real time. Under 700 keV ion irradiation, the platform reveals clear fluence-dependent reductions in thermal conductivity near the surface—offering a rapid alternative to traditional ex-situ techniques. To further support research under extreme thermal conditions, a new infrastructure has been established, featuring a precision-controlled heating stage capable of reaching 1500°C, in-situ optical microscopy, and Raman spectroscopy. This setup enables continuous monitoring of structural changes during high-temperature exposure and irradiation. Together, these capabilities provide critical insights into material degradation mechanisms and support the accelerated development and qualification of advanced materials for demanding environments.
