Abstract

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 alpha-Fe(3)(Si), Fe(23)(C,B)(6), Fe(3)B and Fe(2)B crystalline phases.

摘要

研究了Fe(72)Si(9.1)B(14.8)Cr(2.2)C(1.9)合金的结晶行为。研究了该合金的三种形态：水雾化粉末、快淬带材和完全结晶带材。对粉末形态的该合金进行透射电子显微镜研究发现Fe₂B发生了部分结晶。发现快淬带材完全非晶，未检测到任何晶相的迹象。观察到完全析晶带材中形成了亚稳相。将该合金加热到其结晶温度以上后，由α-Fe₃(Si)、Fe₂₃(C,B)₆、Fe₃B和Fe₂B晶相组成。
