The behavior of tungsten as plasma facing material in fusion environment is investigated using molecular dynamics simulation. Tungsten erosion and surface evolution is simulated during irradiation by carbon and deuterium ions. Non-cumulative pure carbon bombardment on crystal tungsten shows that substrate temperature does not affect carbon trapping rate, implantation depth, and tungsten sputter...

Wire + Arc Additive Manufacturing (WAAM) is an advanced manufacturing technology by inexpensive Gas Tungsten Welding (GTAW) technology. Key microstructural features of the as-built WAAM alloy include large columnar β grains, grain boundary α colonies, and Heat Affected Zone (HAZ) banding, which generally leads to low ductility anisotropy. In this study, Ti–6Al–xV (x = 0, 2, 4) alloys were prepa...

UNLABELLED Adequate polymerization plays an important role on the longevity of the composite resin restorations. OBJECTIVES The aim of this study was to evaluate the effect of light-curing units, curing mode techniques and storage media on sorption, solubility and biaxial flexural strength (BFS) of a composite resin. MATERIAL AND METHODS Two hundred and forty specimens were made of one comp...

Abstract In this article we explore the availability of radiopure tungsten and its potential as high density shield material for low background applications. For compact designs, conventionally, lead is used. Metallic pseudo-alloys reach higher densities up to 19.3 g cm −3 do not exhibit a significant 210 Pb activity, which typical intrinsic contamination in lead. Within several γ -ray screenin...

Ni-based superalloys are the important materials for gas turbines in advanced aeroplane engines . The addition of refractory elements to these superalloys, such as rhenium and tungsten, can significantly improve the hightemperature performance by so-called solid-solution hardening. Although the strengthening effect of refractory elements in Ni-based superalloys have been known for a long time, ...

Abstract A multilayer constrained alumina ceramic metal composite armor is designed in this paper. The effect of interlayer steel thickness on penetration process tungsten alloy piercing projectile studied by the test and finite element simulation. results show that case same layer ceramics equal surface density, thicker plate away from impact is, better support to sandwich is. It beneficial ma...

The effects of elevated temperature at high strain rate a commercial tungsten alloy were investigated. tests carried-out strainrate (from 850 to 2200 1/s) by means Split Hopkinson Tension Bar device on round specimens having diameter and gauge length 2mm 5 mm, respectively. thermal conditions obtained water-cooled induction heating system the specimen mounted SHTB. dependence ultimate tensile s...

A new approach for the development of thermoelectric materials, which focuses on a high-power factor instead large figure merit zT, has drawn attention in recent years. In this context, properties Cu-Ni-based alloys with very high electrical conductivity, moderate Seebeck coefficient, and therefore power are presented as promising low-cost alternative materials applications aiming to have outpu...
