Effect of Fe on Crystallization Process of Zr-Co-Al-(Fe) Bulk Metallic Glasses

摘要：

　　The change in the internal states of Zr56Co28Al16 bulk metallic glass (BMG) upon minor substitution of Co with Fe was investigated for alloys with different compositions of Zr56Co28-xAl16Fex (x = 0,1 and 2,respectively).Results exhibited that the ductile Zr-Co-Al-Fe BMGs were obtained and showed better glass-forming ability (GFA) via a small amount of Co partial replacement by Fe.In addition,the addition of a small amount of Fe enhanced the crystallization process and reduced the activation energy.The micro-alloying with Fe reduced the heat of mixing,which made the rearrangement of atoms easier during the crystallization process.
