摘要：
The effect of hydrogen charging on shear bands and plastic zone during Vickers indentation for Zr65Al7.5Ni10Cu17.5 bulk metallic glass has been studied. The results showed that hardness increased gradually with charging time and reached saturation. The shear bands and the size of the plastic zone on the surface and subsurface of indentation increased evidently when charging time was less then 40 h at i = 10 mA/cm(2) or 10 h at i = 100 mA/cm(2), respectively. After that, the size of the plastic zone began to reduce with charging time because hydrogen blisterings began formation and growth. (c) 2006 Elsevier B.V. All rights reserved.
