不同微观结构Zr55Al10Ni5Cu30块体非晶合金非等温晶化动力学研究
Non-isothermal Crystallization Kinetics of Zr55Al10Ni5Cu30 Bulk Metallic Glass with Different Microstructure
摘要
Abstract
Zr55Al10Ni5Cu30 bulk metallic glasses with different microstructure were obtained by changing the melting time of the master alloy ingots,and the non-isothermal crystallization kinetics was investigated by differential scanning calorimeter.The results show that the two Zr55Al10Ni5Cu30 bulk metallic glasses with different microstructure have the similar apparent activation energy of crystallization.The reason is that the structure of the primary phase of the bulk metallic glasses is different fi om their local ordering structure,which results in little effect of the size of medium and short range ordering on the nucleation and growth of crystallization phase.关键词
