TEM Study of the Orientation Relationship Between Cementite and Ferrite in a Bainitic Low Carbon High Strength Low Alloy Steel

, 2005
Two different bainitic structures are observed in a steel depending on the sample heat treatment. The different types of bainitic structures exhibit different orientation relationships between cementite and the ferrite matrix.

Determination of Carbon Content in Bainitic Ferrite and Carbon Distribution in Austenite by Using CBKLDP

, 1998
Convergent beam Kikuchi line diffraction patterns taken with a 10nm-diameter electron beam have been used to determine the lattice parameter and hence the carbon concentration in both ferrite and austenite.

Hydrogen Embrittlement of Nanostructred Bainitic High Strength Steel [PDF]

, 2019
Characterization of nanostructured bainitic high strength steel revealed austenitic and bainitic-ferritic constituents. Hydrogen diffuses through austenite slower than bainitic ferrite. Discovering the effective hydrogen diffusion coefficient, subsurface

Evaluation of Shear-Punched Surface Layer Damage in Ultrahigh-Strength TRIP-Aided Steels with Bainitic Ferrite and/or Martensite Matrix Structure

Metals
The damage to the shear-punched surface layers such as strain-hardening, strain-induced martensite transformation, and micro-void initiation behaviors was evaluated in the third-generation low-carbon advanced ultrahigh-strength TRIP-aided bainitic ...

Achieving an excellent balance of strength, plasticity, and stretch flangeability in a 1000 MPa grade TRIP-assisted bainitic ferrite steel

Journal of Materials Research and Technology
To address the requirements for safety enhancement, weight reduction, and emission reduction, a novel transformation-induced plasticity-assisted bainitic ferrite (TBF) steel was processed by involving a pre-quenching (PQ) process. This steel was designed
