| 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 report using an improved Lock-in Infrared Thermography (LIT) to rapidly measure and map thermal properties and characterize the microstructure defects, such as porosities, of Advanced and Additive Manufacturing (Electric Field Assisted Sintering and Directed Energy Deposition) produced materials. Using the numerical model developed on MOOSE, samples with heterogeneity microstructure (such as functionally graded materials) and irregular geometry can also be successfully characterized. |
