Summary: This study investigates the influence of build orientation on the microstructure and macroscopic response of SLM Ti-6Al-4V alloy under varying strain rates. Compression tests at different rates were conducted on specimens with different build orientations. The results show that the yield strength and strain-hardening rate are influenced by both build orientation and strain rate. Fractographic examination reveals the coexistence of ductile and brittle fractures, with noticeable differences in fracture morphology for dynamically loaded specimens.

Summary: This study focuses on simulating the heat treatment of Ti-6Al-4V parts produced through SLM printing, aiming to predict the residual stress field and distortions. Different creep tests were conducted to determine material parameters, showing that high temperature behavior is not significantly affected by initial porosity and material parameters change notably above 873K due to microstructure transformation. Experimental and numerical distortions were compared, showing good agreement.

Summary: This study investigates the selective laser melting (SLM) technique to produce Ti-6Al-4V-Zn titanium alloy. The addition of 0.3 wt.% zinc is explored to improve the strength and ductility of SLM Ti-6Al-4V alloys. The results show that the specimen treated with a vacuum heat treatment process at 800-4-FC exhibits the most favorable overall mechanical properties. In addition, zinc acts as a stabilizing element for the beta phase, enhancing the erosion resistance and corrosion impedance of Ti-6Al-4V-Zn alloy. Furthermore, the incorporation of trace amounts of Zn improves the impact toughness and high-temperature tensile mechanical properties of SLM Ti-6Al-4V-Zn alloy.

Summary: This study evaluated the fatigue behavior of additively manufactured Ti-6Al-4V via Laser Powder Bed Fusion in three different conditions: as-built, heat-treated, and hot isostatically pressed (HIP'ed). The results indicate that fatigue failure in as-built and heat-treated conditions was mainly driven by early-stage crack growth, while crack initiation was the main controlling factor for fatigue deformation of HIP'ed samples. Furthermore, a strong correlation between impact energy and fatigue limit was observed. The findings were based on detailed microstructural and crystallographic characterization, as well as mechanical testing. The as-built and heat-treated conditions exhibited poor fatigue response compared to HIP'ed, which can be attributed to lower levels of porosity.

Summary: The study revealed that vanadium enriches around the boundary of alpha phases with increasing annealing temperature to 973 K, and alpha ' phases transform into alpha+beta at 973 K. The typical alpha' martensite microstructure transforms to fine-scale equiaxed microstructure at 973 K and significantly coarsens with increasing annealing temperature to 1273 K. The SLM Ti-6Al-4V alloy annealed at 973 K exhibits a well-balanced combination of strength and ductility.

Summary: As-built, SLM-printed Ti-6Al-4V parts have brittle microstructures due to the formation of metastable a'-phase martensite. Post-processing heat treatments are needed to alleviate residual stress and decompose the martensite. This research evaluates the effect of unconventional 'cyclical' heat treatment parameters on grain morphology, phase composition, and mechanical performance, and compares it to a typical lamellar microstructure.

Summary: TiB + La2O3/Ti-6Al-4V composites were prepared using selective laser melting technology, and the effect of LaB6 content on the composite samples’ quality, microstructure evolution, and mechanical properties was investigated. The results showed that with increasing LaB6 content, the sample’s relative density decreased, TiB precipitates changed their structure, and the dislocations accumulated around the reinforcements, leading to enhanced tensile strength. Compared to pure Ti-6Al-4V sample, the addition of 3 wt% LaB6 significantly increased hardness, tensile strength, and reduced wear volume. This study demonstrated the potential of using LaB6 to improve the mechanical performance of titanium alloys in additive manufacturing.

Summary: Titanium surface treated with titanium oxide nanotubes has been used in studies to investigate the effect of surface topography on cell fate. However, there is significant variation in the predicted optimal diameter of the nanotubes among different studies. A model is proposed to explain cell adhesion to a nanostructured surface by considering cell protrusions into titanium nanotubes and adhesion to the surface. The results suggest that it is feasible to tune the surface topology to enhance the proliferation and differentiation of cells compatible with the given surface geometry.

Summary: This study investigates the use of Mg-3Y alloy as an alternative to the WE43 alloy. The results show that the omission of RE and Zr elements does not compromise the corrosion resistance and degradation rate of the W3 alloy compared to the WE43 alloy, while maintaining appropriate biocompatibility. It is also shown that the decrease in mechanical strength caused by the omission of RE and Zr can be compensated for by severe plastic deformation.

Summary: Titanium beta alloys have lower Young's modulus than commonly used alloys, making them more similar to bone tissue. Ion implantation can improve the tribological properties of these alloys, but its effect on corrosion behavior is uncertain. Surface analysis showed the presence of nitrides and the elimination of unstable oxides after nitrogen ion implantation. Electrochemical measurements demonstrated that ion implantation does not negatively impact the corrosion behavior of the material. The Ti-36Nb-6Ta alloy exhibited the best corrosion resistance, with the combination of niobium and tantalum nitrides contributing to its improved performance.

Summary: Two novel ignition-resistant magnesium alloys, Mg-2Gd-2Y-1Ca and Mg-2Nd-1Y-1Ca, were prepared by ECAP and compared with four commercial alloys. The novel alloys exhibited a mean grain size of around 1μm and a dense distribution of small secondary phase particles. Mechanical testing showed that the novel alloys had significantly higher strength than the commercial alloys (except WE43), but lower ductility due to Ca segregation. The ignition temperature of the novel alloys was considerably improved (around 950°C) by the presence of Gd/Nd, Y and Ca. This study demonstrated the high strength and high ignition temperature of the novel alloys in the ultrafine-grain condition.

Summary: This study investigates the local peri-implant pH changes caused by sterile inflammation and bacterial and fungal infections. A sensing electrode based on polyaniline and poly(2-methyl-2-oxazoline) on a titanium alloy support is developed for early detection of these pathologies. The results show statistically significant pH changes caused by different bacteria and yeast, with potential for identifying the nature of the infection. The developed electrodes have a wide pH response range and can contribute to the next generation of biosensors.

Summary: The focus of this study was to investigate the combined effects of microbial transglutaminase (MTG) treatment and exopolysaccharides (EPS) on the rheological and microstructural properties of yoghurt. MTG was applied to milk before fermentation and simultaneously with yoghurt culture. Short-term and long-term fermentations were conducted using EPS-producing and non-EPS-producing cultures. Treatment with MTG increased gel strength and viscosity, especially when applied simultaneously with the culture. The presence of EPS further enhanced these properties and reduced syneresis, resulting in improved texture and acceptability.

Summary: Advanced techniques were used to investigate the corrosion mechanism of the as-ECAPed Zn-0.8Mg-0.2Sr alloy, revealing the formation of thin oxide layers on the surface before exposure and their participation in corrosion product formation. The segregation of Mg on the Zn grain boundaries was observed, leading to localized corrosion attacks. Micro-galvanic cells and crevice corrosion mechanism were identified as the initiation process for degradation, resulting in an corrosion rate of 0.36 mm center dot a (-1).
