A novel in-situ scanning electron microscope (SEM) characterization technique for observing phase transformation is developed and its results studied compared to well-founded experimental ex-situ methods as well numerical modelling of bainite formation. Phase kinetics are between the SEM, dilatometry test mean field Cellular Automata (CA) models. Microstructural evolution during EBSD CA model r...

Systematical experimental data on density, molar volume and the surface tension, measured in electromagnetic levitation, has been summarized for liquid Ti-V system. The optical dilatometry method as well oscillating drop technique have employed to investigate temperature- compositional dependence. A linear decrease density tension with increasing temperature observed all investigated compositio...

The effect of austenite deformation on carbon partitioning and transformation to athermal isothermal martensite, bainite during quenching (QP) is described for three steel compositions: Fe-0.3C-0.6Si-1.1Al, Fe-0.3C-1.0Si Fe-0.3C-0.5Si-0.5Al. Microstructures were characterized using SEM-EBSD, TEM XRD. Austenite decomposition kinetics was investigated dilatometry. Deformation close the no-recryst...

Abstract This contribution addresses the effect of heating and cooling rates on microstructure a double soaked medium-Mn 0.16C-5 Mn‑1.6Al‑0.2Si steel with an increased Al addition. The obtained results show that differences in applied have small investigated steel. Some dilatometer response during final to room temperature were noted. Moreover, some changes fraction retained austenite at partic...

in this investigation, continuous cooling transformations and microstructures have been studied in detail in a low carbon ti-nb bearing microalloyed steel by means of dilatometry, metallography and hardness measurements. the results indicate that when the cooling rate is greater than 1˚c/s, the dilatation curve is associated with a major dilatation at relatively low transformation temperatures,...
