形成能力,热稳定性和 Mg65Cu25Tb10 体积的结晶化行为的玻璃上的 5%Ni 增加的效果金属性的玻璃用 X 光检查 diffractometry,微分扫描热量测定和传播被调查电子显微镜学。Ni 增加的小数量减少在结晶化激活精力由于重要减少形成能力和热稳定性的玻璃。结晶化动力学的分析在非结晶的 Mg65Cu20Ni5Tb10 把证据给熄灭在里面的原子核的存在。最后的结晶化产品为 Mg65Cu25Tb10 和 Mg65Cu20Ni5Tb10 是基本上一样的。
The effects of 5%Ni addition on the glass forming ability, thermal stability and crystallization behavior of Mg65Cu25Th10 bulk metallic glass were investigated using X-ray diffractometry, differential scanning calorimetry and transmission electron microscopy. The small amount of Ni addition reduces the glass forming ability and thermal stability due to a significant decrease in the crystallization activation energy. Analyses of crystallization kinetics give evidence to the existence of quenched-in nuclei in amorphous Mg65Cu20Ni5Th10. Final crystallization products are basically same for Mg65Cu25Tb10 and Mg65Cu20Ni5Tb10.
