| 中文摘要 | The deformation behaviour and the depth dependent hardness variation in Ni - P amorphous alloy were investigated by nanoindentation. It was found that in addition to circular shear bands around the indent and on the indent surface, which have been previously observed, straight shear bands on the indent surface were also formed during nanoindentation. The indentation depth dependent hardness in the metallic glass is not modelled by the conventional dislocation based strain gradient theory for crystalline materials; instead it can be well described by a function of the inverse square root of the indentation depth. The structure evolution beneath the indentor is proposed to be the probable cause for the length scale dependent properties in metallic glass. |
