Abstract

The kinetics of bcc crystallization and subsequent transformations in an Fe43Cr25Ni20B12 glass were monitored by magnetic measurements and X-ray diffrsaction. The metastable bcc phase (ferrite) which forms first transforms to austenite and a boride during isothermal annealing. At low temperatures the ferritegrows without significant partitioning of Fe, Cr and Ni. Increasing the annealing temperature results in alloy partitioning which is directly linked with the ferrite decomposition.
