Summary: This work reports the highest yield strength and elongation in an Mg-Y-RE-Zr alloy produced by an additive manufacturing (AM) process. A combination of a large-diameter welding wire and pulsed current was used to inhibit the oxidation of WE43 alloy fabricated by quasi-directed energy deposition using electric arc (quasi-DED-Arc). The results show that the amount of Y2O3 in this work is only 2-5% of that of the sample produced by powder bed fusion (PBF) reported previously. Moreover, the variable solidification conditions and in-situ heat treatments induced by the multiple thermal cycles (MTCs) were found to result in an inhomogeneous microstructure along the building direction, which are responsible for the variations in mechanical properties. The WE43 alloy exhibits excellent mechanical properties due to the intrinsic heat treatment that occurs during the build process. The 8th layer exhibits a maximum tensile strength of 347 MPa and a good elongation of 7.1%, which exceeds the strength-ductility combinations for cast WE43 alloy. The strengthening mechanisms in different layers have been discussed. A physical model depicting the microstructural transformation during quasi-DED-Arc has been proposed based on the measured thermal cycling data and microstructure observations.

Summary: The study investigated the pre-strain annealing strengthening effect on extruded Mg-1.0Gd-1.5 Zn (wt.%) alloy with different grain sizes. The microstructure evolution of the alloy under various conditions was examined using various microscopy techniques. The results showed a grain size-dependent pre-strain annealing strengthening effect in the alloy, with larger grain sizes exhibiting higher strengthening effect due to hindrance of twin growth and increased nucleation of new twins.

Summary: High temperature heat treatment Mg-0.69Sn-0.69Y alloy exhibited a high damping capacity (0.201 at epsilon=1 x 10-3) and a very low critical strain amplitude at room temperature (epsilon cr1=2.97 x 10-5), which can be ascribed to the combined effects of purified matrix phase and subgrain interfaces. The substructure is unstable and the damping capacity decreases with temperature increment.

Summary: In this study, four typical twin-like interfaces were identified as incoherent grain boundaries. It was proposed that the interaction of multiple twinning contributes to the formation of these boundaries, and a special angle close to 90 degrees is formed due to alternative tensile and compression twinning under uniaxial loading.

Summary: Friction stir processing can produce materials with very fine grains, but the differences between the advancing side and the retreating side result in an uneven stir zone. Processing the material from both sides helps eliminate this difference, although the mechanical properties of the processed material are inferior to the parent material despite grain refinement.

Summary: The influence of a 1050 degrees C annealing on the minimum creep rate of Ti-6Al-4V alloy produced by additive manufacturing was investigated. Experimental data analysis showed that the alloy annealed at the highest temperature had lower creep rates. This improvement was attributed to the presence of extended alpha-beta interfaces and a small volume fraction of Ti3Al particles.

Summary: This study analyzed the creep response of AISI 316 and AISI 316 L, taking into account the presence of fine particles precipitated during creep exposure. A recent model developed for particle-strengthened alloys was used to describe the minimum creep rate dependence on applied stress. The same model, in combination with a composite model, was applied to describe the creep behavior of additively manufactured AISI 316 L, which had a different microstructure compared to wrought materials.

Summary: Austenitic stainless steels used in osteosynthesis devices are prone to crevice corrosion. Studies have shown that austeno-ferritic duplex stainless steel is a suitable alternative due to its resistance to crevice corrosion and superior mechanical properties. However, the use of duplex stainless steel for biomedical applications is still under discussion due to potential harmful effects in magnetic fields.

Summary: Commercially pure titanium plates were friction-stir welded using a tool with a tungsten carbide pin. The FSWed material was defect-free and lacked WC particles. The TMAZ exhibited refined equiaxed grains, possibly due to dynamic recrystallization. The improved mechanical properties of the TMAZ were attributed to grain refinement, mechanical twinning, and increased dislocation density.

Summary: This study investigates the effects of Re and Ta interactions on the precipitation of the TCP phase in experimental alloys under long-term thermal exposure. The study finds that microstructure segregation is not fully eliminated even with standard heat treatment, and the interaction between Re and Ta enhances the formation of the TCP phase. Thermodynamic calculations and first-principles analysis reveal that Re significantly improves the driving force of TCP phase precipitation. The study also observes a phase transition from the sigma-phase to the P-phase, with Ni playing a crucial role in the diffusion process.

Summary: The microstructures and corrosion resistance of TC11 components were significantly improved using a high-power, high-speed laser metal deposition (LMD) process and subsequent post-heat treatment, with greater improvements observed in the deposition direction. The significant improvement of corrosion resistance in the deposition direction is mainly due to the weakening of the charged galvanic corrosion effect between the non-interlayer zone and interlayer zone.

Summary: In this study, the microstructures and mechanical properties of interphase precipitation strengthening micro-alloyed steels were investigated. The addition of Cr was found to increase the yield strength without significant decrease of ductility. Thermodynamics analysis revealed that the addition of Cr led to grain refinement and decrease of sheet spacing of nanoprecipitates. Calculations showed that the decrease of interphase-precipitated carbides sheet spacing and the refinement of grain size were responsible for the strength enhancement of Cr microalloyed steel.

The composites consisted of long TiB nanowires as 'web' and hybrid TiC and Ti3Si particles as 'nodes'. The enhanced strength of these composites was attributed to the synergistic load transfer of the hybrid reinforcements. This study provides a promising design approach for developing high-performance composites with high reinforcement content, utilizing polymer instead of traditional ceramic powder.
