摘要: 利用X射线衍射(XRD)和差示扫描量热仪(DSC)分析了Fe50.6Cr23.3Mo8.4C8.4B9.3 (at.%)合金粉末和薄带的相组成和等时加热的晶化行为。结果表明，粉末和薄带为完全非晶态，所有的等时DSC曲线均显示出明显的玻璃转变。当加热温度不超过993 K时有两个放热峰，分别对应于α-Fe以及χ-Cr6Fe18Mo5和(Fe, Cr, Mo)7C3相的析出。粉末比薄带展示出更高的玻璃转变温度Tg、晶化开始温度Tx和两个放热峰峰值温度Tp1、Tp2，提高幅度约6~15 K。然而，粉末的过冷液相区宽度ΔTx为71.4 K，稍低于薄带(78.6 K)。由Tp1和Tp2计算的粉末的表观激活能Ea1和Ea2分别为344.4 kJ/mol和398.3 kJ/mol，低于薄带(485.6 kJ/mol和487.4 kJ/mol)。
Abstract: The phase composition and crystallization behavior of Fe50.6Cr23.3Mo8.4C8.4B9.3 (at.%) alloy powder and ribbon were analyzed by X-ray diffraction (XRD) and isochronous heating using differential scanning calorimetry (DSC). The results show that the powder and ribbon exhibit fully amorphous phase. All isochronal DSC curves exhibit an obvious glass transition, as well as two exothermic peaks corresponding to the precipitation of α-Fe and χ-Cr6Fe18Mo5 plus (Fe, Cr, Mo)7C3 phases respectively when heating temperature does not excess 993 K. Glass transition temperature Tg, crystallization onset temperature Tx, and two exothermic peak temperature Tp1, Tp2 of powder are all higher than that of ribbon by the improving amplitude of 6 - 15 K. However, the supercooled liquid region ΔTx is 71.4 K for powder, which is slightly lower than that for ribbon (78.6 K). Apparent activation energy Ea1 and Ea2 calculated according to Tp1 and Tp2 are 344.4 kJ/mol and 398.3 kJ/mol for powder, respectively, which is lower than that for ribbon which are 485.6 kJ/mol and 487.4 kJ/mol, respectively.
