Pulsed Thermal Tomography Nondestructive Examination of Additively Manufactured Reactor Materials and Components. Third Annual Progress Report

Pulsed Thermal Tomography Nondestructive Examination of Additively Manufactured Reactor Materials and Components (Final Technical Report)

“…Creating microscopic calibrated defects in high strength metal is a challenge with LPBF process involves sintering SS316 and IN718 metallic powder grains with the average diameters of 20µm and 40µm, respectively. A scanning electron microscope (SEM) micrograph of SS316 TrueForm powder grains is shown in Figure 2(a) [39]. The histogram of particle diameter distribution is plotted in Figure 2(b).…”
