Acoustic emission and digital image correlation (DIC) were used to determine mechanical properties of six biomedical alloys from a single compression deformation experiment. Layered sample of six Ti-(20–35)Nb-7Zr-0.2O alloys was prepared by spark plasma sintering. All six layers were deformed in compression at once. Advanced use of DIC allowed us to separate the deformation in each layer and determine the flow curve of each alloy. Simultaneous use of acoustic emission provides insight into active plastic deformation mechanisms. Nb content in the studied alloys significantly affects ductility of the material as well as shape of the compression flow curve suggesting different plastic deformation mechanisms in the studied alloys. Presented methods provide high-throughput determination of mechanical properties allowing efficient optimization of alloy composition.
