摘要
We investigate the crystallization kinetics of Co48Cr15Mo14C15B6Er2 bulk metallic glass. It is found that Co48Cr15Mo14C15B6Er2 alloy shows extraordinary glass-forming ability, and a fully glassy rod with a diameter of 10mm can be formed, Thermal analysis exhibits that this glassy alloy has a high thermal stability, Johnson-Mehl-Avrami analysis of isothermal differential scanning calorimetry demonstrates that the crystalline phases homogeneously nucleates at a constant rate and grows linearly at a constant rate in three dimensions in the supercooled liquid of the glassy alloy.
