| Abstract Scope |
Thermal transport properties are among the most important physical properties in energy related applications as they directly tie to energy transport efficiency. Moreover, they are sensitive to the existences of defects and thus can be used to characterize microstructure. Here we reported the experimental approaches 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 Advanced Manufacturing and Additive Manufacturing produced 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). The progress of developing PTR/LIT based in-situ processing monitoring capabilities will also be presented. |
