Strain partitioning and localization were investigated in a high-Mn steel (17.1 wt.% Mn) during tensile testing by a correlative probing approach including in-situ synchrotron X-ray diffraction, micro- digital image correlation (μ-DIC) and electron

Austenite reversion in AISI 201 austenitic stainless steel evaluated via in situ synchrotron X-ray diffraction during slow continuous annealing

Autor: I.R. Souza Filho, Paulo Atsushi Suzuki, Christian Gauss, Hugo Ricardo Zschommler Sandim, D. R. Almeida Junior, Maria José Ramos Sandim

Publikováno v: Materials Science and Engineering: A. 755:267-277

In situ synchrotron X-ray diffraction was used to track real-time austenite reversion in AISI 201 austenitic stainless steel deformed to a true strain of 0.34 under tensile testing. The deformed material was continuously annealed from 100 °C up to 8

Reconstructing the austenite parent microstructure of martensitic steels: A case study for reduced-activation Eurofer steels

Autor: Kahl Dick Zilnyk, Dierk Raabe, D. R. Almeida Junior, Hugo Ricardo Zschommler Sandim

Publikováno v: Journal of Nuclear Materials. 516:185-193

A computer program was employed to reconstruct the parent microstructure from electron backscatter diffraction maps taken from martensite. The reconstruction is based on a given user-selected orientation relationship. Two reduced-activation ferritic-

Misorientation distribution between martensite and austenite in Fe-31 wt%Ni-0.01 wt%C

Autor: Dierk Raabe, D. R. Almeida Junior, Hugo Ricardo Zschommler Sandim, Paulo Rangel Rios, Kahl Dick Zilnyk

Publikováno v: Acta Materialia. 143:227-236

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
