In this research, ultrafine-grained Cu-7at%Al-3at%Ni alloys with a twin structure and precipitates were prepared by cold rolling+aging+cold rolling+aging (CR+ACA) and multi-directional forging+aging+cold rolling+aging (MDF+ACA). In contrast with the un-deformation sample, significant increases in strength were obtained by MDF+ACA and CR+ACA, reaching 803.7 MPa and 722.8 MPa respectively, while maintaining a good elongation of 9.5 % and 8.4 […]

The goal of this work was to measure the impact of a Dielectric Barrier Discharge (DBD) plasma treatment (DBD) on the adhesion properties of the most common wood-based materials used in industry, namely particle boards and medium-density fiberboard (MDF). Samples made of particle board and MDF were finished with melamine foil or water-based painting. Before the finishing procedure, contact angles were

VVOCs with a retention range below C6 has become one of the main indoor pollutants that negatively affect human health. Most studies have focused on the emission of VOCs from furniture and decorative materials, seldom considering VVOCs. To close this gap, a 15-L environmental chamber, combined with a multi-absorbent tube, was used for gas sampling. Emissions

Experiments were performed in order to evaluate the effect of deformation amplitude (Δε) and cumulative strain (ε) on the thermal stability of Copper 99.8% pure, after processing with 8 and 48 Multidirectional forgings (MDF) cycles at room temperature with Δε ≈ 0.075 (MDF0.075) or 2 and 12 MDF cycles with Δε ≈ 0.30 (MDF0.30), leading to cumulative deformations of

In the present study, various processes have been carried out on the extruded Mg-4Zn-4Al-0.6Ca-0.5Mn (wt%) alloy to achieve a low corrosion rate Magnesium (Mg) alloy. Microstructure studies revealed that the extruded alloy contained the needle-like Al-Mn second phases and the globular and elongated (Mg, Al)2Ca + ϕ(AlMgZn) phases. After solution treatment, the area fraction of the second phase

Screw joint is a prevalent connection method in furniture, buildings, and structures, which plays an essential role in the integrity and durability of a wooden structure. Considering such benefits, the impact of core and face layers density, screw direction, pilot hole diameter, screw type, and water immersion on screw axial withdrawal resistance of medium-density fiberboard
