RESUMO

In this work, the effect of C4+ and Cl4+ ion irradiation with 25 MeV energy on the hardness and shear banding feature of Ti40Zr25Be30Cr5 bulk metallic glass was studied. Depth-sensing nanoindetation and microindentation were applied for characterizing the multiple-scaled hardness and shear band patterns during plastic deformation. It is shown that the Cl4+ ion irradiation leads to an obvious softening of the sample surface, and distinctly affects the serrated flow feature during plastic deformation. In contrast, C4+ ions have little effect on the hardness and shear band patterns. Besides, the mechanism for the change of the mechanical properties and plastic deformation behavior after ion irradiation was also discussed.
