Summary: Ti2AlC and Ti3AlC2 are part of the MAX phases, a family of layered compounds. The study tests a composite approach to improve the brittleness of these compounds. Surface severe plastic deformation (SSPD) was conducted on a bulk MAX compound and a MAX/TiAl2 composite using surface mechanical attrition treatment (SMAT). The presence of intergranular TiAl2 effectively prevented failure in the composite, resulting in a surface hardening gradient extending down to a depth of 250 μm.

Summary: The role of interfaces in phase formation during severe plastic deformation (SPD) was investigated using molecular dynamics simulations. It was found that dilute solute additions that segregate to interphase boundaries can greatly extend the solubility limits of the bounding phases, providing a novel approach to processing nanocomposite alloys by SPD. The results were rationalized using a modified effective temperature model, which showed that increasing the interface strength leads to higher effective temperatures and higher solubilities.

Summary: SMAT treatment at cryogenic temperature can improve the fatigue resistance of 5553 beta-metastable Ti alloy by generating compressive residual stresses, reducing roughness, deepening martensite formation, and increasing the size of kink bands. Conversely, SMAT treatment at room temperature does not provide any improvement in fatigue performance, possibly due to the appearance of subsurface crystallographic defects caused by the larger grain size.

Summary: This study investigated the spheroidization behavior of TiBw/Ti composites subjected to isothermal multi-directional forging with different strain rates. The results showed that strain rate significantly influenced the microstructure spheroidization process, with dynamic recovery at high strain rates and dynamic recrystallization dominating at lower strain rates. Additionally, the relationship between crystallographic orientation and imposed strain played a key role in the spheroidization process, indicating the importance of heterogeneous deformation phenomena in the alpha colony.

Summary: The tensile deformation behavior of high-strength nanostructured Cu-Si solid-solution alloys processed by high-pressure torsion was studied at room and low temperatures. Increasing Si concentration led to significantly increased tensile strength. This strengthening effect was achieved through grain refinement and increased dislocation density caused by severe plastic deformation with the influence of Si addition on the decreasing stacking fault energy of the Cu-Si alloy.

Summary: The corrosion behavior of AA5457 alloy sheet is complex and involves trenching around coarse Si-rich particles, crystallographically-grown large pits, and the formation of multiple tiny pits around Si-rich nanoparticles. Bending AA5457 changes the shape and distribution of Si-rich coarse particles, increases the dislocation density in the material, especially around Si-rich nanoparticles, all leading to a lower corrosion behavior in the bending area.

Summary: The effect of interstitial elements on the thermal stability of ultrafine-grained Ti alloys was investigated. It was found that UFG Ti 99.99% and Ti Grade 2 showed relatively stable microstructure and mechanical properties up to 200℃ and 400℃, respectively. Surprisingly, both materials exhibited a discontinuous yielding phenomenon after annealing above their thermal stability range.

Summary: This study investigates the microstructure and chemical composition of a novel metastable TNTZ alloy modified by DLIP using a Nd:YAG laser. SEM, TEM, and STEM were used to analyze the microstructure, while XPS and APT were employed for chemical composition analysis. The study reveals significant microstructure evolution in the TNTZ alloy surface region due to DLIP treatment, along with local chemical heterogeneity of the alloy that was not considered before in design. The laser treatment homogenizes the remelted zones and influences surface properties.

Summary: The interaction between interstitial elements and screw dislocations in hexagonal titanium has been determined using ab initio calculations. O, N, and C act as repulsive obstacles, while H is attracted to the dislocation, especially to the pyramidal stacking faults forming the dislocation core. Thus, the studied solutes provoke different strengthening mechanisms, such as dislocation cross-slip or binding.

Summary: The study demonstrates that laser processing improves the biological responses of titanium surfaces. The Direct Laser Interference Patterning (DLIP) method is proposed as a single-step functionalization technique for pre-modified titanium surfaces in biomedical applications. Calcium phosphate coatings were deposited through immersion in Hank's solution to evaluate the biomedical potential of modified Ti substrates. X-ray photoelectron spectroscopy, scratch tests, scanning electron microscopy, and energy dispersive spectroscopy were employed to investigate the bioactive effect and adhesion force of the Ca-P coating. Overall, the results confirm the positive influence of laser treatment on bone-like apatite formation and surface wear resistance.

Summary: In this study, the corrosion behavior of two alloys, Ti-29Nb-13Ta-4.6Zr and Ti-45Nb, with similar amounts of β-phase stabilizers, was compared. The corrosion resistance was analyzed in a PBS+H2O2 solution, simulating post-operative inflammation conditions. The results showed that the Ti-29Nb-13Ta-4.6Zr alloy had significantly higher corrosion resistance compared to Ti-45Nb, as evidenced by electrochemical impedance spectroscopy and ion-release measurements. Microscopic analysis also revealed that a thinner layer of oxidation products was formed on the Ti-29Nb-13Ta-4.6Zr alloy surface. These findings suggest that Nb does not play a beneficial role in tailoring the corrosion resistance of Ti-29Nb-13Ta-4.6Zr under simulated inflammatory conditions.

Summary: The study aimed to compare the influence of microstructural and textural changes on the hardening by annealing effect in cold-rolled titanium. Different thickness reductions were applied to produce ultrafine-grained (UFG) Ti Grade 2, and the hardening effect was observed through a short-time annealing process. The results showed that the hardening effect was not related to texture changes, but rather to the annihilation of mobile dislocations and the ordering of the dislocation substructure within coarse grains.

Summary: The aim of this study was to investigate the impact of manufacturing defects on the high-cycle fatigue life of a commercially pure Ti Grade 2 produced by a laser beam powder bed fusion (PBF-LB) process. The high-cycle fatigue performance of PBF-LB Ti Grade 2 was compared to its ultrafine-grained (UFG) counterpart processed by hydrostatic extrusion. Despite similar yield strength, UFG Ti Grade 2 exhibited a significantly higher endurance fatigue limit compared to PBF-LB Ti Grade 2, and the size of manufacturing defects greatly affected the high-cycle fatigue life.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
