Low-temperature bainite in low-carbon steel

WebVandaag · Lower carbon concentration at low temperatures results in weak variant selection in bainite, whereas it is the reverse in the case of martensite. Lower carbon concentration (0.2 mass%) at 400 °C results in a single variant, whereas high carbon concentration (more than 0.2 mass%) results in multiple variants [90].
