Multilayered laminate structures obtained by coating of ultrafine-grained metallic materials with bioactive and multifunctional composite coatings are considered for biomedical applications. Laser-assisted densification multiple using laser cladding selective melting is an alternative route to reduce the risk early implant failure allowing faster cheaper fabrication. To understand cooperative r...

High-purity Ni was processed by high-pressure torsion (HPT) at room temperature under an imposed pressure of 6.0 GPa and a rotation rate 1 rpm through 1/4 to 10 turns, samples were then examined using Electron Back-Scattered Diffraction (EBSD) microhardness measurements. The results show that the grain size low-angle boundaries (LAGBs) gradually decrease with growth HPT revolutions while values...

Cu-to-Cu thermal compression bonding (TCB) has emerged as a promising solution for ultrafine pitch packaging in 3D integrated circuit technologies. Despite the progress made by conventional TCB methods achieving good mechanical strength of Cu bonds, processes generally require high temperature and pressure, which may degrade performance reliability device. Therefore, it is imperative to investi...

Generally, AZ31 magnesium alloys have poor formation ability near room temperature. This material, with ultrafine grains, usually exhibits excellent superplasticity at high Therefore, the preparation of materials suitable microstructures to obtain is an important goal. In this study, double-side FSW (Friction Stir Processing) process was applied on AZ31Mg alloy microstructure ultra-fine grains....
