摘要
用机械合金化法制备了不同成份的 Al- Ni- L a- Cu非晶合金 .经 X射线衍射仪、透射电子显微术和示差扫描量热仪 (DSC)热分析研究表明 ,随着合金中 Cu含量的增加 ,Al- Ni- L a- Cu的非晶形成能力逐渐增强 ,晶化温度逐渐降低 .
A morphous powder of Al rich Al Ni La Cu alloy was prepared by mechanical alloying. The alloy was studied with X ray diffraction, transmission electron microscopy and differential scanning calorimetry. As a result, with the amount of copper increasing, the glass forming ability of Al Ni La Cu alloy is gradually increased, but the crystalline temperature is gradually decreased.
