Fabrication of Amorphous Mg55Ni35Si10 Powder by Mechanical Alloying
摘 要
采用机械合金化方法制备出了Mg55Ni35Si10非晶合金粉体,采用XRD、HRTEM、FESEM以及DSC试验,对所得粉末的微结构、相组成、颗粒形貌及热稳定性进行了表征.结果表明:对于配比为Mg55Ni35Si10的粉末,经约68h的球磨可以获得完全非晶态的合金粉末,其晶化温度约为420℃,证明该材料具有相对较高的热稳定性.

Abstract
Amorphous Mg55Ni35Si10 alloy powder had been synthesized by mechanical alloying technique.The microstructure,phase and thermal stability of the resultant powders were characterized by XRD,HRTEM,FESEM and DSC electron croscopy,transmission electron microscope and differential scanning calorimetry.The results show that an amorphous Mg55Ni35Si10 powder can be generated after milled for about 68 hours and the powder has a crystallization temperature of around 420℃,suggesting relatively high thermal stability than reported results.
