Influence of a short thermal treatment on the superelastic properties of a titanium-based alloy
Scripta Materialia, 2010•Elsevier
The effect of a very short aging treatment (360s at 873K) on the superelastic properties has
been investigated on the ternary Ti–20Nb–6Zr (at.%) titanium-based alloy. Such short
thermal treatment is shown to be an efficient way to obtain a recrystallized microstructure
with ultrafine β grains of about 1–2μm. In addition, the associated mechanical properties
display an outstanding improvement in superelastic properties, with 3.2% of elastic recovery
combined with high tensile strength of around 750MPa.
