1Structural Modification of Al65Cu16.5Ti18.5 Amorphous Powder through Annealing and Post Milling: Improving Thermal Stability显示文摘To improve thermal stability of the Al65Cu16.5Ti18.5 amorphous powder,structural modification of the amorphous powder was performed through annealing and post milling.Annealing above the crystallization temperature(Tx) not only induced nanoscale intermetallics to precipitate in the amorphous powder,but also increased Cu atomic percentage within the residual amorphous phase.Post milling induced the amorphization of the nanocrystal intermetallics and the formation of Cu9Al4 from the residual amorphous phase.Thus,a mixed structure consisting of amorphous phase and Cu9Al4 was obtained in the powder after annealing and post milling(the APMed powder).The phase constituent in the APMed powder did not change during the post annealing,which exhibited significantly improved thermal stability in comparison with the as-milled amorphous powder.Zhen Tan Lu Wang Yunfei Xue Xingwang Cheng Long Zhang 2016Journal of Materials Science & Technology2016,32,12:1
2Zr-Al-Ni-Cu合金非晶形成范围的Miedema模型预测显示文摘运用扩展Miedema模型及Toop几何模型,计算了Zr-Al-Ni-Cu四元系中各三元合金及四元合金的形成焓与系统组成间的分布关系.利用对应三元合金焓值的加权计算,获得了Zr-Al-Ni-Cu四元合金的最佳非晶形成组分.与现有实验结果相对比,计算结果及机械合金化实验均表明,利用合金的形成焓值可以较好地预测系统的非晶形成范围.刘衡 尹洪波 周仁杰 张怀亮 龙卧云 2018广西师范学院学报(自然科学版)2018,35,1:0
