Tempering of Low-Temperature Bainite [PDF]
Metallurgical and Materials Transactions A, 2017 AbstractElectron microscopy, X-ray diffraction, and atom probe tomography have been used to identify the changes which occur during the tempering of a carbide-free bainitic steel transformed at 473 K (200 °C). Partitioning of solute between ferrite and thin-films of retained austenite was observed on tempering at 673 K (400 °C) for 30 minutes.
