Analysis of phase transformations in Fe-(Co)-B-Si-(P)

The subsequent crystallization stages of bcc-Fe and borides were determined by the electrical resistivity, differential scanning calorimetry and thermogravimetry measurements, the important temperature parameters and intervals of stability and phase transformations were estimated. The phase analysis performed by TEM and XRD diffraction identified different crystallization products formed in the course of transition from the amorphous state. Morphology of nano-sized Fe grains in amorphous matrix and the transformation of remaining matrix into boride phases were observed we compared the effects of different additives onto the transformations curves and on the resulting structure.
