Abstract: Abstract We characterized the morphology, substructure and crystallography of lenticular martensite in a Fe-Ni-C alloy by means of electron backscatter diffraction and scanning electron microscopy. Electron backscatter diffraction maps were used to determine the orientation… read more here.

Abstract: Abstract The structure and crystallography of martensite-austenite (M-A) constituent in the intercritically reheated coarse-grained heat affected zone (ICCGHAZ) of X100 (690 MPa) pipeline steel weld joint was studied via multi-scale characterization. The results suggested that majority… read more here.

Abstract: Abstract We have studied here the distribution of carbon and alloying elements in the martensite-austenite (M-A) constituent in intercritically reheated coarse-grained heat-affected zone (ICCGHAZ) of a high-strength pipeline steel using atom probe tomography (APT). Notable… read more here.
