In this research, Glass Form Ability (GFA) has been investigated in the new class of Fe-based amorphous
alloys. Indeed, the main purpose is to evaluate the effects of alloying with niobium on glass form ability of Fe55-xCr18Mo7B16C4Nbx (X=0, 3, 4, 5) alloys. Vacuum induction melting (VIM) was utilized for production of primary
ingots and melt spinning process was used for production of thin ribbons required for kinetic and structural investigations. Kinetic analysis was done using
the data obtained from Differential Scanning Calorimetry (DSC) tests. Results showed that GFA and viscosity were enhanced by Nb alloying. It was also determined that devitrification transformation was accomplished in alloys by nucleation and growth mechanisms.
