Anisotropy of ultrafine-grained alloys under impact loading: The case of biomedical niobium-zirconium

The anisotropy-impact response relationship of a biocompatible niobium-zirconium (NbZr) alloy with an ultrafine-grained microstructure was investigated. The current findings not only shed light on the micromechanisms dictating the impact response in the microstructures studied, but are also encouraging with respect to the use of NbZr in orthopedic and dental implants.
