To investigate and verify the degree to which forming properties of low plasticity materials are improved at room temperature using granular medium (GMF) process 500 °C, a coupled Eulerian–Lagrangian unit calculation model was established special mold designed conduct GMF experiment for titanium alloy sheets under different-shaped pressing blocks. Then, three-coordinate measuring machine, sizes...

Titanium is notable for its biocompatibility and is used as biologic implant material across surgical specialties, especially in metal-sensitive individuals. However, rare cases of titanium hypersensitivity reactions are reported in the literature. This article discusses the properties and biological behavior of titanium and provides a thorough review of the literature on reported cases, diagno...

Background We previously conducted a first-in-human clinical study of articular cartilage repair using autologous chondrocyte sheets and confirmed the regeneration of hyaline-like cartilage in all eight patients. However, regenerative medicine with autologous chondrocyte sheets requires the harvesting of tissue from healthy regions, and the quality of this tissue varies between individuals. To ...

AIM The aim of the study is to investigate the galvanic corrosion potential of metal injection molding (MIM) brackets to that of conventional brackets under similar in vitro conditions with nickel-titanium and copper nickel-titanium archwires. MATERIALS AND METHODS Twenty-five maxillary premolar MIM stainless steel brackets and 25 conventional stainless steel brackets and archwires, 0.16 inch...

Titanium matrix composites (TMC) represent a perspective materials category with potential applications in many important fields like aerospace constructions, automotive industry, ship structures, sports and households objects, and others. A titanium matrix composite is constituted of a titanium or titanium alloy – matrix and reinforcements materials, which are usually ceramics in form of parti...

The aim of the research presented in this article was to determine value friction coefficient using a simple tribological test and build an empirical model with use radial basis function artifi-cial neural networks. tests were carried out on specially designed simulator that allows sheet metal strip be drawn between two fixed dies. materials sheets Ti-6Al-4V titanium alloy thickness 0.5 mm. var...

Wide use of titanium alloys results from their unique physical and chemical properties 1 . Combination of low density and improved corrosion resistance with good plasticity and mechanical properties determines application of titanium alloys in such industries as aviation, automotive, power and shipbuilding industries or architecture as well as medicine and sports equipment. Despite numerous adv...

Carbon nanotubes (CNTs) have excellent chemical durability, mechanical strength and electrical properties. Therefore, there is interest in CNTs for not only electrical and mechanical applications, but also biological and medical applications. We coated titanium, a common material for dental implants, with multiwalled carbon nanotubes (MWCNTs). First, titanium was aminated and covered with colla...
