Fig. 1: Post-necking properties of the Ti-12Mo (wt.%) alloy compared with other high strength alloys^{20,21,22,23,24,25,46,47,48,49,50,51,52}.

a True stress-true strain curves of Ti-12Mo compared with classical Ti alloys. A cross indicates the true fracture stress and true fracture strain. A dashed line represents the extrapolation between the true tensile curve recorded up to necking and the true fracture stress—true fracture strain. The red colored area represents the integration performed to estimate the work of fracture \(W_{\mathrm{f}}\), which is used as an indicator of the fracture toughness. b Comparison of the work of fracture \(W_{\mathrm{f}}\) versus true uniform strain \({\it{\epsilon }}_{\mathrm{u}}\) of several alloys. The major families of alloys are grouped by colored circles. A black dashed line indicates the limit of the best combination of both properties. Ti-12Mo alloy is located among the best materials on the map, while its outstanding mechanical properties with respect to classical Ti alloys are clearly demonstrated. The mechanical properties of the HEA and some DP steels result from internal unpublished PhD theses.
