Bainitic reaction kinetics in ductile iron contained according to Ukrainian standard (weight %) 3.603.80 carbon, 2.60-2.80 Si, 0.12 Mn, 0.60 Cu and additionally alloyed by Mo (0.15-0.20) has been studied. It was found that the overall transformation kinetics becomes slower as transformation temperature increase. This is because more intensive redistribution of carbon into austenite at higher te...

In this study, structural and crystallographic properties of phase transformations in Fe–Mn– Mo–Si (Mn = 15.14 wt.% 18.45 wt.%) alloys were investigated. The effects heat treatment temperature on microstructure investigated by Scanning Electron Microscopy (SEM) Metallurgical (MM). addition to this, revealed using Transmission (TEM) X–Ray Diffraction (XRD) methods. the samples subjected at 750 ...

The development of the quenching and partitioning (Q&P) process has prompted an interest in isothermal transformation presence a pre-existing phase such as martensite. prior martensite is known to accelerate overall kinetics bainite formation, both 1-step 2-step Q&P process. underlying mechanisms behind this phenomenon are not fully understood. Also, nature product (isothermal and/or bainite) f...
