In-situ SEM investigation of fatigue crack propagation through …
The microstructures in the HAZ and other regions are examined using SEM, metallographic images, and electron backscatter diffraction (EBSD). Next, the FCGRs for WAAM, HAZ, cross-weld zone, and BM specimens are compared.
EBSD characterization of secondary microcracks in the heat …
2015年5月17日 · In order to get better understanding of the mechanism of cleavage fracture in the heat affected zone (HAZ) of X100 pipeline steel, secondary microcracks underneath the brittle fracture surface of a Charpy impacted sample with the notch located in the HAZ were characterized using electron backscattered diffraction.
Structural analysis by SEM-EBSD of the transverse section of the ...
2024年11月17日 · Notably, the heat-affected zone (HAZ) in DSS 2205 showed random texture due to ferritization and grain coarsening. EBSD analysis at the interfaces revealed epitaxial grain growth from partially melted grains while energy-dispersive X-ray maps disclosed complex interdendritic particles in the weld metal (WM).
