Towards the ab initio based theory of the phase transformations in iron and steel [PDF]
, 2017 Despite of the appearance of numerous new materials, the iron based alloys and steels continue to play an essential role in modern technology. The properties of a steel are determined by its structural state (ferrite, cementite, pearlite, bainite ...

Object kinetic Monte Carlo study of the effect of grain boundaries in martensitic Fe-Cr-C alloys [PDF]
, 2016 Fe-Cr-C alloys with chromium concentrations in the range from similar to 2 to 12 wt.% form ferritic-martensitic structures by rapid cooling from the austenite state already in the presence of relatively low carbon concentrations.

The impact of hydrogen on the ductility loss of bainitic Fe–C alloys [PDF]
, 2016 The influence of hydrogen on the mechanical properties of generic lab-cast Fe-C bainitic alloys is studied by tensile tests on notched samples. The bainitic microstructure is induced in a 0.2% C and 0.4% C Fe-C alloy by an appropriate heat treatment. The
