Abstract: The grain refinement mechanism of ferrite dynamically transformed (DT) from austenite is investigated in a 10Ni–0.1C steel. For decades, it has been debated whether dynamic recrystallization (DRX) contributes to the grain refinement of DT ferrite.… read more here.

DOI: 10.1016/j.actamat.2016.11.004
Abstract: Abstract Low-temperature gas-phase nitridation has been studied in interstitially-hardened 17-7 precipitation-hardening stainless steel. After nitridation, conventional transmission electron microscopy reveals that delta ferrite grains in such alloys show a uniform weak diffraction contrast. Chemical analysis… read more here.

DOI: 10.3390/ma14154154
Abstract: We performed a three-dimensional (3D) analysis of ferrite grains recrystallized in low-carbon steel during annealing. Cold-rolled specimens were heated to 723 K and held for various periods. The 3D morphology of ferrite grains recrystallized during… read more here.
