Plasma Electrolytic Oxidation (PEO) was applied to extruded ZM21 Mg alloys improve their corrosion resistance in a chloride-containing environment. PEO carried out DC mode and voltage control fluoride-free electrolyte. Potentiodynamic polarization tests 3.5 wt.% NaCl aqueous solution neutral salt spray (NSS) were out. Microstructural profilometric characterization, as well NSS performed differe...

This paper models hot compression testing using a dilatometer in loading mode. These small-scale tests provide high throughput at low cost, but are susceptible to inhomogeneity due friction and temperature gradients. A novel method is presented for correcting the true stress-strain constitutive response over full range of temperatures, strain-rates strain. The nominal from used predict offset c...

statement of problem: element release from dental casting alloys into the oral environment is of clinical concern and is considered to be a potential health problem to all patients. purpose: the aim of this study was to investigate the metallic ion release of four base metal alloys. materials and methods: two ni-cr (minalux and supercast) and two co-cr alloys (minalia and wironit) were examined...

Abstract Numerical methods can accelerate the design of alloys with improved material properties. One approach is coupling multi-criteria optimization CALPHAD-based models alloy While this technique has already yielded promising new Nickel-base superalloys, applicability to CoNi-base not yet been investigated. These show properties for application as wrought high-temperature materials. We desig...

Abstract Titanium alloy Ti6Al4V has been widely applied to medical, automotive, and aerospace industries due its excellent properties such as high strength corrosion resistance. On the other hand, additive manufacturing (AM) technology can give freedom of design products. In order spread AMed products, joining wrought products are required, it is important understand joint characteristics. this...

Abstract This work investigates the machinability characteristics of additively manufactured Ti6Al4V titanium alloy workpieces in finishing machining using ball end mills on 45° inclined surfaces. The surface finish results were compared with ones from milling trials wrought samples same cutting conditions. Optical profilometry and scanning electron microscope imaging used to compare different ...

Novel magnesium-based materials are ideal candidates for use in future aviation vehicles because they extremely light and can therefore significantly increase the range of these vehicles. They show very good castability, easy to machine be shaped into profiles or forgings used as components next generation aerial vehicle construction. In case a large number identical components, high-pressure d...
