Study of the Mechanical Behaviour of a Zr-Based Metallic Glass Rod Using Micro- and Nano-Indentation
Dept. de Física, Universitat Autònoma de Barcelona, 08193 Bellaterra, Spain.
ABSTRACT
The mechanical properties of a Zr55Cu30Al10Ni5 metallic glass rod are investigated by Vickers microhardness and depth-sensing nanoindentation. The alloy exhibits a relatively large hardness which decreases when increasing the maximum applied load. Serrated flow is also observed during nanoindentation. Both effects are related to deformationinduced mechanical softening.
