Abstract

The structure of metastable Fe₃B boride and its change during phase transformations of alloys of the Fe–B system from amorphous to equilibrium crystalline state have been investigated by X-ray diffraction analysis and transmission electron microscopy. It is shown that metastable boride undergoes the Fe₃B (\(I\bar {4}\)) → Fe₃B (\(P{{4}_{2}}{\text{/}}n\)) → Fe₃B (P) structural transformations and retains its lattice parameters during amorphous-phase crystallization. The thermal stability of each lattice depends on the B concentration in the alloy.

非晶态铁基合金结晶过程中亚稳相的形成

摘要

通过X射线衍射分析和透射电子显微镜研究了亚稳Fe ₃ B硼化物的结构及其在Fe–B系合金从非晶态到平衡晶态的相变过程中的变化。结果表明，亚稳硼化物经历了Fe ₃ B（\（I \ bar {4} \））→Fe ₃ B（\（P {{4} _ {2}} {\ text {/}} n \））→Fe ₃ B（P）的结构转变，并在非晶相结晶过程中保留其晶格参数。每个晶格的热稳定性取决于合金中的B浓度。
