“…As expected, lower temperatures and higher strain rates lead to higher compressive strength. The sample deformed at T = 800 • C withε = 0.01 s −1 exhibits the sharp yield point similarly to the tensile flow curves performed at room temperature [13]. On the other hand, flow curves measured at higher temperatures did not exhibit the sharp yield point because the temperature is sufficiently high to activate diffusion of oxygen in matrix and prevent pinning dislocations by interstitial oxygen atoms.…”

“…However, their strength is approximately only one half of that of Ti64. Small amount of oxygen addition, typically 0.3%-0.5%, has a great strengthening effect on this type of β-Ti alloys [8][9][10][11] and adding more than 0.5% of oxygen, as in Ti-35.3Nb-7.3Zr-5.7Ta-0.7O, yields even higher strength, sharp yield point and deformation strengthening [12,13]. The addition of 0.7% of oxygen raises Young's modulus to the value of 80 GPa that is still significant improvement to 110 GPa of Ti64.…”

“…In the rolled conditions, the yield points are significantly "sharper" compared to forged conditions. The reason for the occurrence of a sharp yield point was the interaction of dislocations with interstitial oxygen atoms [21,38]. Table 5.…”

“…In contrast, in alloys containing α phase (either α + β alloys or metastable β alloys aged to α + β condition), the maximum allowed oxygen content is limited typically to 0.2 wt% to avoid embrittlement [20]. Interstitial strengthening by oxygen has been thoroughly studied in our previous work on as-cast Ti-35Nb-7Zr-6Ta based alloys with various oxygen contents [21].…”

“…Thus, many strengthening strategies involving diverse thermomechanical treatment strategies to positively influence the fatigue strength were in focus of research. Whereas work hardening for instance increases the static strength, fatigue strength remains mostly unaltered [15][16][17][18][19][20][21][22][23][24]. The most significant effect in case of TiNb-based alloys seems to be possible due to precipitation and grain boundary hardening in order to effectively hinder dislocations to move through the material and thus, positively influence the fatigue limit [16,18].…”
