{225} habit planes in martensitic steels: from the PTMC to a continuous model

Baur, Annick PaulineCayron, CyrilLogé, Roland2017-02-152017-02-152017-02-15201710.1038/srep40938https://infoscience.epfl.ch/handle/20.500.14299/134320WOS:000392322800001Fine twinned microstructures with {225}γ habit planes are commonly observed in martensitic steels. The present study shows that an equibalanced combination of twin-related variants associated to the Kurdjumov-Sachs orientation relationship is equivalent to the Bowles and Mackenzie’s version of the PTMC for this specific {225}γ case. The distortion associated to the Kurdjumov-Sachs orientation relationship results from a continuous modeling of the FCC-BCC transformation. Thus, for the first time, an atomic path can be associated to the PTMC.martensitesteelhabit planecrystallography{225} habit planes in martensitic steels: from the PTMC to a continuous modeltext::journal::journal article::research article
