Probing grain size effect in the superelastic Ti-20Zr-3Mo-3Sn alloy using spherical nanoindentation

Résumé

Grain size effect on superelasticity was investigated in Ti-20Zr-3Mo-3Sn alloys for the same crystallographic texture and for a broad grain size range from 7 μm to 180 μm. The dependence of superelasticity on grain size was studied by spherical nanoindentation. Results displayed the same tendency as that observed during tensile tests. The small-sized β grains favored the martensitic transformation, and exhibited the greater superelasticity. It is confirmed that spherical nanoindentation is capable of characterizing superelasticity and is sensitive enough to probe grain size effect in superelastic alloys. It is also shown that β grain size evidently affects indentation hardness and modulus. © 2021 Elsevier Inc.
