Summary The crystallization behaviour of Fe 72 Si 9.1 B 14.8 Cr 2.2 C 1.9 alloy was studied. Three forms of the examined alloy were studied: water‐atomized powder, as‐spun ribbon and fully crystallized ribbon. Transmission electron microscopy studies of the examined alloy in the form of powder revealed partial crystallization of Fe 2 B. The as‐spun ribbon was found to be fully amorphous, and no evidence of any crystalline phases was detected. Formation of metastable phases in the fully devitrificated ribbon was observed. The examined alloy, heated to above its crystallization temperature, consisted of α‐Fe 3 (Si), Fe 23 (C,B) 6 , Fe 3 B and Fe 2 B crystalline phases.
