Effect of Tempering Temperature on Hydrogen Embrittlement of SCM440 Tempered Martensitic Steel. [PDF]
Materials (Basel), 2023 The effect of tempering temperature on the hydrogen embrittlement characteristics of SCM440 tempered martensitic steels was investigated in terms of their microstructure and hydrogen desorption behavior. The microstructures were characterized using scanning and transmission electron microscopy, as well as X-ray diffraction and electron backscattered ...

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.

High-Temperature Tempered Martensite Embrittlement in Quenched-and-Tempered Offshore Steels [PDF]
Metals, 2017 Embrittlement induced by high-temperature tempering was investigated in two quenched-and-tempered offshore steels. Electron backscattering diffraction and analysis of Kernel average misorientation were applied to study the coalescence of martensite; transmission Kikuchi diffraction coupled with compositional mapping was used to characterize the ...
