摘要
采用单辊急冷法制备了Fe68Ni1Al5Ga2P9.65B4.6Si3C6.75非晶薄带。用XRD、DSC研究合金的晶化动力学过程。结果表明:合金的玻璃转变和晶化行为均具有动力学效应,其晶化类型为初晶型和随后的共晶型反应。用Kissinger法计算得到的Eg、Ex、Ep1、Ep2分别为703、373、446、723kJ/mol,Eg远大于Ex,表明该合金具有较高的热稳定性。
Amorphous ribbon of the Fe68Ni1Al5GaEP9.65B4.6Si3C6.75 alloy was prepared by melt-spun method, and the crystallization kinetics process was investigated by XRD and DSC. The results indicated that both the glass transition and crystallization behavior of the alloy have kinetic effect. The crystallization types are primary and later eutectic reaction. Eg, Ex, Ep1 and Ep2 of the alloy are 703,373, 446 and 723 kJ/mol, respectively, by the Kissinger equations. And Eg is much higher than Ex, which reveals that the alloy has good thermal stability.
