“…[ 50 ] The deformation path also affects both the triggering stress and the yield stress of metastable β Ti‐alloys due to the asymmetry of deformation‐induced martensite formation.

“…An increase in strain rate leads to a significant increase in triggering stress: in Ti–10V–2Fe–3Al and Ti–10V–3Fe–3Al alloys, the triggering stress is more than doubled when the strain rate is increased by four orders of magnitude from 10 −3 to 10 2 s −1 . [ 14,49 ] However, this trend is not followed at very high strain rates exceeding 10 3 s −1 .

“…[49,51] For example, the values of 268 MPa under tension and 203 MPa under compression were reported for an annealed Ti-10V-2Fe-3Al alloy consisting of β phase only. [49] Martensite transformation starts in the elastoplastic transition region (Region II in Figure 3c,d) and dominates until the second yield point (Figure 3b). Prolific formation of martensite (%70%) in the slow stress rising region (Region III in Figure 3c,d) corresponds to a significant increase in work hardening rate.…”

The microstructural and mechanical evaluation of 9% Ni steel with Flux-Cored Arc Welding was performed with two different Nibased weld metals: Inconel 625 and Hastelloy 609. Weld metals showed the microstructural change depending on the temperature gradient and crystal growth rate for each region during the cooling after welding. At the bottom of the weld metal, which is rapidly cooled in contact with the cold base metal, a cellular/planar growth was exhibited due to a large temperature gradient and low crystal growth rate. While, columnar dendrites were exhibited in the central region cooled relatively slowly and precipitates were observed in the interdendritic region. In the low-temperature toughness test, the absorbed impact energies were 89 and 55 J for Inconel 625 and Hastelloy 609, respectively. When Inconel 625 is used as the weld metal compared to Hastelloy 609, the high content of the γ stabilizer and martensite start temperature decreasing elements leads to the formation of a thicker γ-phase layer and thinner martensite layer in the transition region. In addition, high content of these elements suppresses the martensite transformation and maintains the stability of the weld joint interface even at low temperatures, resulting in the higher absorbed impact energy.
