Microstructure and electrochemical properties of rapidly solidified alloy Ml(NiCoMnTi)_5

摘要

The microstructure and electrochemical properties of MINi_3.7Co_0.75Mn_0.5Ti_0.05 alloys prepared by both rapid solidification and conventional cast methods were comparatively investigated. SEM and XRD studies showed that the microstructure of conventional cast alloy cooled slowly from its melt was of dendrite, where obvious segregation of Mn and trace second phase TiNi_3 were found.
