“…Furthermore, phase mapping ( Figure 3) showed an increased amount of α-phase (hcp-Ti) after processing. The same result was found by other authors, 12,13 who observed a similar α+β microstructure in conventional alloys.…”

“…10,11 Indeed, in the literature, SPD has been widely described as an important metallurgical processing route to improve the mechanical performance of metals and alloys. [12][13][14][15] A welldesigned sequence of hot, warm, and cold metallurgical deformation can be employed to acquire tailored bulk nanostructures and optimize mechanical responses for implant material performance. 13,16 SPD technique using equal channel angular pressing (ECAP) has been used to create ultrafine grain sizes in many metals and alloys.…”

“…In contrast, the α´ martensite could be partially or completely converted into equilibrium (α + β) phases during the hot deformation at higher compression temperatures and lower strain rates, leading to relatively lower stress softening rates. Additionally, for the instability of the plastic flow [27], abnormal hardening is observed as indicated in the red rectangular dashed box in Figure 6c Figure 6 demonstrates the measured true stress-strain curves. The flow stress under all process conditions rapidly peaks at a relatively small strain and then is followed by extensive flow softening.…”

“…Grain refinement is an effective approach to enhance the mechanical properties of metals and alloys [15,16]. Zhang et al [17] investigated the influence of three different microstructures on the plastic flow behavior of Ti-6Al-4V. The α' martensitic initial microstructure is more beneficial for achieving grain refinement.…”
