Abstract

The effect of heat treatment on tensile properties, especially pseudoelastic behaviour of hot-rolled Ti-25Nb-3Zr-3Mo-2Sn (wt.%) alloy has been studied. The as-rolled alloy shows high strength due to the presence of nanoscale co and a precipitates, but it suffers from limited ductility. The conventional solution plus ageing treatment improves the ductility, but it has an adverse effect on the psudoelastic properties. By applying flash treatment (500 °C for 2 min), the alloy is found to have not only balanced strength and ductility, but also improved psudoelastic properties, such as higher recovery strain and lower elastic modulus. The microstructural changes associated with the flash treatment are revealed.
