Abstract

Nanoindentation tests were conducted on three different bulk metallic glasses (BMGs) using both the Berkovich and cube-corner tips. Larger displacement and more pronounced pop ins were observed under cube-corner tip in all three materials. Pop-in distance and indentation depths were used to determine the plastic shear resistance of different BMGs under nanoindentation. The plastic shear resistance was found to be independent of the shape of the indenter and dependent only on material; it is linearly scaled with the shear modulus of a material. © 2008 American Institute of Physics.
