TL;DR: An open-celled porous Cu with adjustable pore characteristics and mechanical properties has been successfully prepared by using NaCl as space-holders via a sintering-dissolution process for the first time.
Abstract: An open-celled porous Cu with adjustable pore characteristics and mechanical properties has been successfully prepared by using NaCl as space-holders via a sintering-dissolution process for the first time. Examination of macroscopic and microscopic morphologies as well as the quasi-static compressive test for the resultant material was also carried out.

TL;DR: In situ TiO(2) nanotube layer/Ti biocomposite has better and wider application prospects as a dental implant biomaterial and had very good antibacterial activity to resist Streptococcus mutans.
Abstract: The TiO(2) nanotube layer was in situ synthesized on the surface of pure titanium by the electrochemical anodic oxidation. The diameter of nano- TiO(2) nanotubes was about 70~100 nm. The surface morphology and phase compositions of TiO(2) nanotube layers were observed and analyzed using the scanning electron microscope (SEM). The important processing parameters, including anodizing voltage, reaction time, concentration of electrolyte, were optimized in more detail. The photocatalytic activity of the nano- TiO(2) nanotube layers prepared with optimal conditions was evaluated via the photodegradation of methylthionine in aqueous solution. The antibacterial property of TiO(2) nanotube layers prepared with optimal conditions was evaluated by inoculating Streptococcus mutans on the TiO(2) nanotube layers in vitro. The results showed that TiO(2) nanotube layers/Ti biocomposites had very good antibacterial activity to resist Streptococcus mutans. As a dental implant biomaterial, in situ TiO(2) nanotube layer/Ti biocomposite has better and wider application prospects.

TL;DR: In this article, the benefits of non-destructive testing, online monitoring and in situ machining are discussed, and strategies on how to manage residual stress, improve mechanical properties and eliminate defects such as porosity are suggested.
Abstract: Depositing large components (>10 kg) in titanium, aluminium, steel and other metals is possible using Wire + Arc Additive Manufacturing. This technology adopts arc welding tools and wire as feedstock for additive manufacturing purposes. High deposition rates, low material and equipment costs, and good structural integrity make Wire+Arc Additive Manufacturing a suitable candidate for replacing the current method of manufacturing from solid billets or large forgings, especially with regards to low and medium complexity parts. A variety of components have been successfully manufactured with this process, including Ti–6Al–4V spars and landing gear assemblies, aluminium wing ribs, steel wind tunnel models and cones. Strategies on how to manage residual stress, improve mechanical properties and eliminate defects such as porosity are suggested. Finally, the benefits of non-destructive testing, online monitoring and in situ machining are discussed.
