Proton conduction underlies many important electrochemical technologies. A family of new proton electrolytes is reported: acid-in-clay electrolyte (AiCE) prepared by integrating fast carriers in a natural phyllosilicate clay network, which can be made into thin-film (tens micrometers) fluid-impervious membranes. The chosen example systems (sepiolite-phosphoric acid) rank top among the solid conductors terms conductivities (15 mS cm-1 at 25 °C, 0.023 -82 °C), stability window (3.35 V), and...
Borides are usually hard and brittle materials; however, we report the synthesis of superplastic nanostructured NdB6 ceramic powders, counter to conventional wisdom that borides always brittle. We investigate through strain engineering, can be made extremely ductile if lattice is compressively strained highly defected, based on transmission electron microscopy (TEM) density functional theory (DFT) calculations. In this study, conditions were designed CALPHAD modelling, powders successfully...
Although Direct Metal Laser Melting (DMLM), a powder bed fusion (PBF) Additive Manufacturing (AM) for metallic materials, provides many advantages over conventional manufacturing such as almost unlimited design freedom, one of its main limitations is the need support structures beneath overhang surfaces. Support are generally in contact with surfaces to physically prop them up; therefore, they be removed after due not constituting part component design. The removal supports process sequence...
Yüksek ısı transfer kabiliyeti, enerji absorbe edebilme ve ses izolasyonu özelliklerinden dolayı kafes yapılar havacılık, otomotiv biyomedikal sanayii başta olmak üzere bir çok alanda kullanılmaktadır. Kafes yapıların bu kabiliyetleri üzerinde farklı proses geometrik parametreler etkili olmaktadır. Farklı endüstriyel uygulamalarda, ilgili yapısının uygun ile birlikte kullanılmasının, uygulama sonucu elde edilen verimi arttıracağı bilinen gerçektir. Bu çalışma, Taguchi deney tasarımı...
Abstract Al-Si metal matrix composites have generally been manufactured using casting methods. Powder metallurgy has used as an alternative manufacturing technique to obtain more homogeneous and segregation-free products. In this study, 2 wt.-% TiB particle reinforced Al-7 Si were high energy ball milling, cold pressing (at 450 MPa) pressureless sintering 570 °C for h under Ar flow) techniques. The effects of different milling processes, such mechanical alloying at room temperature and/or...
This study reports on the detailed microstructural characterization of Al-12.6 wt.% Si eutectic alloy powders synthesized from Al and elemental starting materials via mechanical alloying (MA) for 4, 6, 8 h, subsequent cryomilling (CM). Mechanically alloyed (MA’d) were cryomilled (CM’d) 10, 20, 30 min in a freezer/mill using liquid N2 gas circulated externally around polycarbonate milling vial containing stainless steel rods. SEM/EDS TEM/EDS mapping analyses revealed presence some embedded...
The present study reports the in-situ synthesis of hybrid powders containing vanadium borides (VB 2 , V 3 B 4 and ) carbide (VC) using powder metallurgy methods. VB -V /VC were synthesized from O 5 C blends via a carbothermal reduction route assisted by mechanical milling. Powder mechanically milled up to h in high-energy ball mill. milling process reduced crystallite size, increased uniformity particle distribution hence reactivity starting powders. As-blended annealed at different...
Improving the printability and high-temperature mechanical performance of high aluminum titanium content Inconel superalloys is interest in aerospace, automotive, energy industries. Therefore, this study explores influence TiB2 on additive manufacturing 939 superalloy (In939) by laser powder bed fusion (LPBF). powders with a size approximately 1-3 µm were decorated surfaces alloy via high-speed blending. Both pure In939 In939+TiB2 samples prepared LPBF varying power scanning speed....
