Nanocrystalline (nc) hexagonal close-packed (hcp) metals are rarely observed to deform by twinning, which is contrary to face-centered cubic metals. Here we report that, after alloying Mg with 10 at.% Ti, deformation twins are observed in an nc Mg–Ti alloy processed by mechanical attrition. The formation of deformation twins is attributed to the alloying effect, which may change the energy path for twinning. These results point to a promising approach to design nc hcp alloys for superior mechanical properties.

Evolution of microstructure and deformation mechanisms in a metastable Fe<inf>42</inf>Mn<inf>28</inf>Co<inf>10</inf>Cr<inf>15</inf>Si<inf>5</inf> high entropy alloy: A combined in-situ synchrotron X-ray diffraction and EBSD analysis
2024, Materials and Design
In this work, a combination of in-situ high synchrotron X-ray diffraction and electron backscattered diffraction were used to systematically investigate the activation and evolution of the deformation mechanisms in an as-cast Fe₄₂Mn₂₈Co₁₀Cr₁₅Si₅ metastable high entropy alloy deformed until fracture at room temperature. This work unveils the critical role of the dual-phase γ-f.c.c. / ε-h.c.p. microstructure on the deformation response of the alloy. The different deformation modes, i.e., slip, transformation induced plasticity (TRIP) and transformation induced twinning (TWIP), were seen to initiate at different loading stresses and then to overlap. Quantitative microstructural characterization, which included the evolution of the phase fraction, stress partitioning, dislocation density, c/a ratio and lattice strain for different planes, was performed to elucidate the role of each phase on the macroscopic mechanical response of the metastable high entropy alloy. Furthermore, the magnitude of the different strengthening contributions has been quantified for the first time.
Exceptional reversed yield strength asymmetry in a rare-earth free Mg alloy containing quasicrystal precipitates
2024, Journal of Magnesium and Alloys
This work reports an exceptional reversed yield strength asymmetry at room temperature for a rare-earth free magnesium alloy containing a mass of fine dispersed quasicrystal (I-phase) precipitates. Although exhibiting traditional basal texture, it owns an exceptional CYS/TYS as high as ∼1.17. Electron back-scattered diffraction (EBSD) and transmission electron microscopy (TEM) examinations indicate pyramidal <c + a> and prismatic <c> dislocations plus tensile twinning being activated after immediate yielding in compression while basal and non-basal <a> dislocations in tension. I-phase particles transferred the concentrated stress by self-twinning to provide the driving force for tensile twin initiating in neighboring grains, thereby significantly increasing the critical resolved shear stress of tensile twinning to possibly the level of pyramidal <c + a> slip, finally leading to the dominance of pyramidal <c + a> slip plus tensile twinning in texture grains. This results in a higher contribution on yield strength by ∼55 MPa in compression than in tension, which reasonably agrees with the experimental yield strength difference (∼38 MPa). It can be concluded that I-phase particles influence deformation modes in tension and in compression, finally result in reversed yield strength asymmetry.
Implications of twinning on the microstructure development, crystallographic texture and mechanical performance of Mg alloys- a critical review
2023, Journal of Magnesium and Alloys
Deformation twinning is profusely activated in the Mg alloys due to lower critical resolved shear stress (CRSS) compared to the non-basal slip systems (prismatic <a> and pyramidal <c + a>) and plays a significant role in texture reorientation, grain refinement and enhancement of mechanical performance. Twinning is a sequential process comprising twin nucleation, twin propagation and twin growth, hence several intrinsic and extrinsic parameters that facilitate or suppress the process have been critically reviewed. The dependence of twinning on the grain size, deformation temperature, favorable grain orientation and shear strain have been thoroughly discussed in the context of published literature and an attempt has been made to provide a benchmark conclusive finding based on the majority of works. Furthermore, the subsequent effect of twinning on the mechanical performance of Mg alloys, including ductility, formability and tension-compression asymmetry has been discussed in detail. Lastly, the stability of twins, including stress and thermal stability, is summarized and critical issues related to pertinent bottlenecks have been addressed.
A study on the effects of laser shock peening on the microstructure and substructure of Ti–6Al–4V manufactured by Selective Laser Melting
2023, Journal of Materials Processing Technology
Ti‐6Al‐4V was fabricated by powder-bed fusion using different laser scanning strategies. The microstructure and deformation properties were investigated in the as-built condition, and also after the material had been subjected to a laser-shock-peening (LSP) treatment. The microstructure in each condition was surveyed using 3D optical microscopy, EBSD, and TEM. The post-manufacture residual stresses were determined. The results indicate a correlation between the residual stresses and the substructures observed in TEM: tensile residual stresses from the surface down to 1 mm depth were observed in the as-built material, corresponding to extensive deformation through twinning of the $\{10 \overset{̅}{1} 2\}$ type and wavy slip structures; while after LSP the alloy showed a variety of dislocation arrangements, especially planar and in significantly higher density, along with $\{11 \overset{̅}{2} 2\}$ twins and with the presence of compressive residual stresses. The findings indicate that the deformation capability is mechanistically aided by the peening process, which effectively promotes the replacement of tensile residual stresses by compressive ones, offering routes for potentially improving the mechanical properties of the additively manufactured Ti‐6Al‐4V, as well as its usability.
Twinning-induced plasticity with multiple twinning modes and disclinations in Mg alloys
2023, International Journal of Plasticity
Twinning-induced plasticity plays a critical role in determining the deformation behaviors of hexagonal close-packed metals (e.g., Mg and Ti), due to the lack of five independent slip systems required for a general deformation. In particular, twinning modes that can accommodate c-axis strain (tensile or compressive) are especially important, which are necessary complementary deformation modes to <a>-type dislocations. However, only limited types of extension twins, e.g., ${10 \bar{1} 2}$ type twin, have been unambiguously identified in the literature, which is theoretically inadequate to accommodate a complex deformation with c-axis extension. Using topological defect theory, here we show that another extension twinning mode, ${11 \bar{2} 6}$ twin, can be formed through reactions between disclinations and ${10 \bar{1} 2}$ twins in Mg-alloys. Based on symmetry of the deformation space, we demonstrate that the ${11 \bar{2} 6}$ twin originates from the inter-connection of correlated deformation paths, which can provide a tensile strain of 5.2% along c-axis and a compressive strain of 4.5% along $〈 11 \bar{2} 0 〉$ . ${11 \bar{2} 6}$ twins can be formed through three formation mechanisms, i.e., direct formation, twin-twin intersection, and double twinning, which are validated by a combination of experimental characterizations and phase field simulations. Our work not only suggests a symmetry-based method to analyze twinning-induced plasticity, but also provides a new insight into the deformation mechanisms and mechanical properties of Mg-alloys.
Formation mechanism of co-axial grain boundaries in a Mg alloy
2023, Journal of Magnesium and Alloys
Due to the insufficient slip systems in hexagonal close-packed structure, twinning is frequently activated to support stable plastic deformation of Mg alloy. In this work, we found four typical twin-like interfaces with misorientations of 102°, 109°, 142° and 149°, respectively, which had not only a shared [11 $\bar{2}$ 0] zone axis of neighboring grains, but also overlapped diffraction spots similar to twins. However, high-resolution transmission electron microscope (HRTEM) analysis revealed that the interfaces in real space deviated from the supposed twinning planes in reciprocal space, i.e. their overlapped diffraction spots. We clarified that the incoherent interfaces were co-axial grain boundaries (CGBs). Additionally, a special angle of θ, close to 90°, between the interface and one side of basal plane, was frequently formed in CGBs. We proposed that interaction of multiple twinning contributes to the formation of CGBs, and the θ is formed due to alternative tensile and compression twinning under a uniaxial loading.
