Abstract Devitrification of mechanically alloyed amorphous Fe70Zr30 at. % compound consists on a two-step process: amorphous → amorphous + bcc Fe + Fe2Zr → Fe2Zr + Fe23Zr6. This sequence is inferred from the evolution of the Mossbauer spectra, the thermomagnetic experiments and the X-ray diffraction (XRD) patterns. Hyperfine parameters for both intermetallics have been obtained from Mossbauer spectroscopy in correlation with the phase identification from XRD results. The broadening of the stable compositional range of Fe2Zr intermetallic above 1000 K is responsible for a strong dependence of the phase fractions on heating and cooling rates. Despite the overlapping of the two processes involved in the devitrification, the individual Avrami exponents of each one have been estimated.

机械非晶化Fe70Zr30合金失透过程动力学及产物研究

摘要 机械合金化非晶 Fe70Zr30 的析晶现象。% 化合物由两个步骤组成：无定形 → 无定形 + bcc Fe + Fe2Zr → Fe2Zr + Fe23Zr6。这个序列是从穆斯堡尔谱的演变、热磁实验和 X 射线衍射 (XRD) 图案推断出来的。两种金属间化合物的超精细参数已从与 XRD 结果的相识别相关的穆斯堡尔光谱中获得。Fe2Zr 金属间化合物在 1000 K 以上的稳定组成范围的扩大导致相分数对加热和冷却速率的强烈依赖性。尽管在反玻璃化过程中涉及的两个过程重叠，但每个过程的 Avrami 指数都已被估计。
