Fracture behavior of cryogenically solidified aluminum-alloy reinforced with Nano-ZrO2 metal matrix composites (CNMMCs)

  Fracture behavior of LM-13 aluminum alloy reinforced with different wt.% of Nano-ZrO2particles, solidified under various shallow cryogenically cooled chills (at -80°C), cast using DMD (disintegrated melt deposition) technique followed by hot extrusion were investigated. The size of the particles dispersed varies from 50 to 80 nm and amount of addition varies from 3 to 15 wt.% in steps of 3 wt.%....

Preparation and characterization of exfoliated nano-composite of polyvinyl acetate and montmorillonite

  To improve the chemical, physical, and mechanical properties of polyvinyl acetate (PVAc), montmorillonite (MMT) was added in the synthesis of PVAc in conventional lab conditions. The final product was studied mainly by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), static tensile, and the rheology was also investigated by the power-law function...
