摘要：

Crystallization of nanosize Fe36Cr12Mo10 phase during annealing process of amorphous Fe55-xCr18Mo7B16C4Nbx (X=0, 3, 4) alloys and also growth mechanisms were studied by X-ray diffraction and differential scanning calorimetric tests as well as TEM observations. Results of TEM observations showed that Fe36Cr12Mo10 phase crystallized in the structures of the alloys in separated perlitic colonies. Furthermore, it is proposed that Fe36Cr12Mn10 phase crystallized in the alloys in mottled morphology and about average size of 10 nm. In addition, kinetic investigations revealed that not only nucleation frequencies but also growth rates were reduced simultaneously by Nb alloying in the alloys. (C) 2012 Elsevier B.V.
