Abstract
The effects of 5%Ni addition on the glass forming ability, thermal stability and crystallization behavior of Mg65Cu25Tb10 bulk metallic glass were investigated using X-ray diffractometry, differential scanning calorimetry and transmission electron microscopy. The small amount of Ni addition reduces the glass forming ability and thermal stability due to a significant decrease in the crystallization activation energy. Analyses of crystallization kinetics give evidence to the existence of quenched-in nuclei in amorphous Mg65Cu20Ni5Tb10. Final crystallization products are basically same for Mg65Cu25Tb10 and Mg65Cu20Ni5Tb10.
