Abstract
The glass forming ability. GFA, has been investigated experimentally and predicted from the transformation kinetics in Fe-Si-B alloy wires. The critical diameter for the formation of an Fe-Si-B amorphous wire increased with the metalloid content up to the amount of 25 at%, then decreased over that content. The amorphous alloy wire with the largest critical diameter has shown the highest value of crystallization temperature at the composition of Fe_(15)Si_(10)B_(15). The larger the diameter of an amorphous wire was, the lower the critical cooling rate that was predicted from the transformation kinetics. The kinetic approach for the prediction of the glass forming ability was successful in view of a good agreement of the measured GFA with the predicted one.
