Carbide precipitation during upper and lower bainite formation in high-carbon bearing steel 100Cr6 is characterized using transmission electron microscopy and atom probe tomography. The results reveal that both ε and θ carbides precipitate in lower bainite isothermally held at 260°C and only θ precipitates form in upper bainite isothermally held at 500°C. ε and θ precipitate under paraequilibrium...
