AbstractA near-α Ti-6Al-7Nb alloy was processed by equal-channel angular pressing (ECAP) and the features of microstructural transformation were studied using EBSD analysis and transmission electron microscopy. The results show a non-monotonic variation in the density of low-angle and high-angle boundaries of the α-phase grains with increasing strain during ECAP. The relationship between the misorientations of the grain boundaries and the mechanical properties of the alloy were examined.

“…The effect of ECAP ( ε 6 ∼ 4.2) on the Ti–6Al–7Nb microstructure: a) a view of a bimodal UFG structure, EBSD; b) a deformed grain of the primary α‐phase, TEM; and c) a typical UFG structure formed from the lamellar (α + β)‐phase structure, TEM. Reproduced with permission . 2017, Elsevier.…”

Study on Corrosion Behavior of Ultrafine-Grained Ti-6Al-7Nb Fabricated by Equal Channel Angular Pressing

“…Recently, ultrafine-grained (UFG) and nanocrystalline (NC) materials processed by severe plastic deformation (SPD) have been widely investigated and found to have unique physical and chemical properties [11][12][13]. Enhanced mechanical behavior and biocompatibility of UFG/NC Ti-6Al-7Nb alloy were acquired after the SPD process [14][15][16][17][18][19]. For instance, Polyakova et al [9] revealed that the tensile strength of the UFG Ti-6Al-7Nb alloy with grain size of 330 nm increased to 1210 MPa after equal channel angular pressing (ECAP), which was 20% higher than observed in coarse-grained (CG) counterparts.…”

“…The grain size would become smaller if the intense shape variation occurred. Recrystallization is one of the most important processes for the elimination of the defects in deformed metals and alloys and therefore the modification of their microstructure and properties [ 20 ].…”
