Summary: In this study, aluminum matrix composites reinforced with different amounts of SiC and Al2O3 nanoparticles were fabricated using powder metallurgy technique. The specimens were characterized by various methods and the results showed that increasing SiC content to 10 wt% improved the hardness and wear resistance of the nanocomposite samples. The dominant wear mechanism was found to be abrasive wear accompanied by oxidation wear. Additionally, the hybrid composite sample containing 7.5 wt% nano SiC exhibited the highest tensile strength compared to other hybrid composites.

Summary: This study proposes and successfully manufactures a novel crack-free Al-Cu-Mg-Si-Ti alloy with improved tensile properties and hot-cracking resistance using laser powder bed fusion (LPBF). The microstructure evolution and strengthening mechanisms are investigated, revealing that pre-precipitated D0 22-Al3Ti particles act as nuclei to refine the grains, leading to strong hot-cracking resistance. Dual-nanoprecipitation of Cu-, Mg-, and Si-rich phases is introduced to enhance the mechanical performance of the alloy.

Summary: Al-Si-Cu-Mg foundry alloys are used in casting process technologies, but their strength properties can be improved through different casting methods. Thixoforming and heat treatment can enhance microstructural refinement and increase strength, while gravity casting and rheocasting may lead to brittle failure.

Summary: This study proposes a Ti powder assisted laser welding strategy for SiCp/2A14Al welded joints. The results showed the formation of regular octahedral TiC and irregular TiAl3 intermetallic dispersed in the Al matrix. Fracture morphology images revealed that the fracture location was the SiC enrichment zone. Additionally, potential technology and design mechanisms for powder feeding laser welding SiCp/2A14Al composites were discussed.

Summary: The hybrid aluminum matrix composites (HAMCs) have gained significant attention due to the synergy between multiple phases. In this study, in-situ AlN-TiC-TiN-Al3Ti/Al inoculation ribbons were prepared and introduced into the Al-Cu-Mn-Ti matrix alloy, leading to improved mechanical properties and refined grain size. The good distribution of nano-particles and the interface matching relationship contribute to the enhanced properties, along with multiple strengthening mechanisms.

Summary: Surface modified CNTs were hybridized with in situ Mg2Si nanoparticles through chemical oxidization to enhance the synergistic strengthening in Mg matrix composites. The tailored volume ratios of CNTs to Mg2Sip using powder thixoforming technology resulted in improved mechanical properties. The strengthening effects of the CNTs-Mg2Sip reinforcements were more effective than using individual CNTs or Mg2Si nanoparticles.

Summary: The corrosion properties of Ti-6Al-4V alloys produced using wire-arc directed energy deposition (DED) with and without different magnetic arc oscillation (MAO) patterns were compared. The relationship between corrosion resistance and microstructural features, such as grain size, geometrically necessary dislocation (GND), and grain orientation spread (GOS), was investigated. The results showed that magnetic arc oscillation improved the corrosion stability of Ti-6Al-4V alloys by refining the grain size, increasing grain boundaries, and enhancing dislocation density. The study also identified the presence of a non-stoichiometric oxide transpassive film on the corrosive surface of Ti-6Al-4V. This research provides valuable insight into the corrosion mechanism of DED-produced Ti-6Al-4V and offers guidance for future process optimization and practical applications.
