Morphology of Widmanstätten and Bainitic Ferrites
Materials Transactions, JIM, 1991 The morphologies of isothermally transformed Widmanstatten and bainitic ferrites in a low carbon low alloy steel have been investigated by means of optical and electron microscopies. In the steel investigated, the Widmanstatten ferrite grains nucleated from the ferrite grain boundary allotriomorphs in the temperature range between 625 and 600 o C ...

Synchrotron X-ray studies of austenite and bainitic ferrite [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008 High-resolution synchrotron X-ray diffraction has been used to conduct in situ studies of the temporal evolution of phases during the isothermal growth of bainite. Two populations of austenitic material were identified: one corresponding to the initial austenite and the other to the carbon-enriched austenite ...

Understanding the interaction between a steel microstructure and hydrogen [PDF]
, 2018 The present work provides an overview of the work on the interaction between hydrogen (H) and the steel’s microstructure. Different techniques are used to evaluate the H-induced damage phenomena. The impact of H charging on multiphase high-strength

steel research international, Volume 96, Issue 7, July 2025.This article investigates the influence of aluminum concentrations on the microstructure and mechanical properties of air‐hardening ductile steels. The reduction of the aluminum contents below 0.5 wt% is unfavorable as it does not ensure sufficient toughness.

Study of Pipeline Steels with Acicular Ferrite Microstructure and Ferrite-bainite Dual-phase Microstructure [PDF]
Materials Research, 2015 Three kinds of X70 steels with the same chemical composition and different microstructures fabricated by varying processes were compared in aspect of the microstructures and mechanical properties using SEM, TEM and tensile testing machine. The experimental results showed that the steel 1 with acicular ferritic microstructure fabricated by thermal ...
