| Abstract Scope |
Thermal transport properties are among the most important physical properties in nuclear materials as they directly tie to energy transport efficiency. Moreover, they are sensitive to defects and thus can be used to characterize the microstructure information. Here we reported the experimental approach of using two Radiometry-based instruments, Photothermal Radiometry (PTR) and Lock-in Infrared Thermography (LIT), to rapidly measure thermal properties and characterize the microstructure defects, such as porosities, of solid materials. The testing samples are manufactured with designed porosities using Advanced Manufacturing technology Electric Field Assisted Sintering (EFAS, or Spark Plasma Sintering, SPS), and Additive Manufacturing technologies Directed Energy Deposition (DED) and Laser Powder-Bed Fusion (LPBF). |
