Raja, Srinivasa V and Ranganathan, Srinivasa (1991) Crystallization characteristics of vitrovac 4040 (Fe39Ni39Mo4Si6B12). In: Zeitschrift für Metallkunde, 82 (12). pp. 907-912.Full text not available from this repository.
The metallic glass Vitrovac 4040 with the composition Fe39Ni39Mo4Si6B12 crystallizes in the order alpha-Fe, hexagonal Ni5Si2 and gamma-(Fe,Ni,Mo) by primary, secondary and polymorphic modes, respectively. The activation energies determined from the non-isothermal kinetics using Kissinger method turn out to be 490, 550 and 449 kJ.mol-1 for the above crystallization reactions. It has been observed that alpha transforms to gamma during annealing. Further, the bct (Fe1-xNix)3B phase has been identified when the glass is annealed above 1023 K.
