Summary: The study investigates the precipitation behavior of the omega(o) phase and creep properties of a Ti-45Al-9Nb-0.5B alloy at intermediate temperatures. It shows that the imposed stress contributes to the nucleation and growth of the omega(o) phase, which can reduce the creep resistance of the material. Additionally, dynamic recrystallization is identified as a primary cause of microstructural degradation.

Summary: A gamma-analogue of the superalloy CMSX-4, without the strengthening gamma '-phase, showed high creep anisotropy and activation energy, indicating that dislocation motion may be controlled by the diffusion of Re atoms.

Summary: The creep age behaviors and tensile properties of an Al-Cu-Li alloy pre-deformed by cold-rolling were investigated. Increasing the pre-deformation promoted the creep strain by dislocation motion mechanism, leading to an increase in strength due to dislocation hardening effect. A further increase in total reduction to 75% resulted in increased creep strain, which was suggested to be a result of decreased hindrance effect on dislocation movement due to serrations in grain boundaries.

Summary: The study focused on grain refinement and enhancement of tensile properties of a Mg-10Al magnesium alloy ingot through strontium addition (up to 1 wt%) and hot working (extrusion process). Addition of 0.05 wt% Sr led to grain refinement and the best strength-ductility combination. Extruded alloys exhibited significantly higher strength and ductility compared to as-cast ingots, with UTS of around 406 MPa and total elongation of about 24% achieved for the alloy with 0.05 wt% Sr.

Summary: The presence of oxygen in commercial titanium and titanium alloys has always caused a ductility loss, but its effect on the macroscopic behavior is still unclear. In this study, the tensile properties of alpha-titanium with varying oxygen contents were investigated. It was found that up to 0.60 wt% of oxygen, no drop in ductility was observed, allowing for exceptional combinations of mechanical properties. The addition of Zr further improved the mechanical properties, surpassing those of the widely used Ti-6Al-4V alloy.

Summary: Micro-additions of 0.25 at.% Mn and/or 0.10 at.% Mo to dilute Al-0.08Zr-0.014Sc-0.008Er-0.09Si alloys affect precipitate evolution and resulting strengths, providing solid-solution strengthening and improving ambient-temperature strength and elevated-temperature creep resistance. Mn-modified precipitates exhibit higher number density, while Mo-modified precipitates display improved coarsening-resistance. Both Mn and Mo additions enhance creep resistance at 300 degrees C, with Mn-bearing alloys showing a more significant effect.

Summary: An improved understanding of dynamic precipitation is crucial for accurately modeling industrial manufacturing processes with high strength Al-alloys. Small angle X-ray scattering (SAXS) is an advanced technique that allows in-situ study of precipitation processes, and using high energy synchrotron X-ray can enable research at higher strain rates. Time resolved SAXS information has been used to evaluate dynamic precipitate evolution models and highlight the importance of considering vacancy annihilation effects at high strain rates.

Summary: In the process development trial, two identical automotive parts were formed from commercial 6082 Al alloy using Hot Form Quench (HFQ). The study compared microstructures and hardness at different locations in the parts, finding that the HFQ process did not result in a loss of hardening potential and that microstructures converged after artificial aging. Tensile tests showed that ductility and failure mechanism were insensitive to small differences in grain boundary microstructure observed in the HFQ component.

Summary: Aluminium matrix composites (AlMCs) of AA7075 aluminium alloy reinforced with 0.5 and 1 wt.% multiwall carbon nanotubes (MWCNTs) were fabricated using powder metallurgy techniques with varying mechanical milling strategies. The dispersion of MWCNTs was found to be influenced by milling conditions and MWCNT content. The best distribution of reinforcements was achieved by milling 7075 powders and MWCNTs in a high-energy cycle (HEBM) at a rotation speed between 1200 and 1300 rpm. Raman spectroscopy showed no damage to the nanotubes during the milling process, and nanoindentation tests revealed that the 7075-0.5 wt.% MWCNT composites had the best mechanical behavior.

Summary: The transfer of basal-to-basal slip across grain boundaries was studied in weakly-textured pure Mg specimens deformed in tension using slip trace analysis and electron back-scatterer diffraction. Basal slip was the dominant deformation mechanism in most grains, and the transfer/blocking of slip at grain boundaries was examined. The active slip system(s) in the grains were determined by analyzing the rotation of grains caused by plastic slip along the basal slip systems. Additionally, the orientation of grain boundaries was measured to determine the twist angle theta.

Summary: The mechanical properties of 2024 aluminum alloy were studied under two different tempers. The T351 temper resulted in high hardness and toughness, while a thermal treatment named TT temper produced the minimum hardness and a lower tensile flow stress. The flow stress decreased and elongation to failure increased above 300°C for both materials. The influence of solutes in solid solutions affected the strain rate, and the stacking fault energy alone could not explain the hot deformation behavior. The synergistic effect of various solutes played a significant role in the entire deformation process.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
