Recent studies have shown that low grain sizes are favorable to improve ductility and machinability in tungsten, as well a resistance ablation spallation, which key properties for the use of this material thermonuclear fusion environment (Tokamaks such ITER). However, one possible incidents during Tokamak operation is leakage air or water from cooling system inside chamber, resulting so-called ...

We assess key plasma surface interaction issues of an all-metal plasma facing component (PFC) system for ITER, in particular a tungsten divertor surface, and a beryllium or tungsten first wall. Such a system eliminates problems with carbon divertor erosion and T/C codeposition, and for an all-tungsten system would better extrapolate to post-ITER devices. The issues studied are sputtering, trans...

introduction one of the best methods in the diagnosis and control of breast cancer is mammography. the importance of mammography is directly related to its value in the detection of breast cancer in the early stages, which leads to a more effective treatment. the purpose of this article was to calculate the x-ray spectrum in a mammography system with monte carlo codes, including mcnpx and mcnp5...

Continuing concern regarding the potential health and environmental effects of depleted uranium and lead has resulted in many countries adding tungsten alloy (WA)-based munitions to their battlefield arsenals as replacements for these metals. Because the alloys used in many munitions are relatively recent additions to the list of militarily relevant metals, very little is known about the health...

Titanium alloys are attracting the attention of researchers and engineers because their unique combination high specific strength, corrosion resistance biocompatibility, but they characterized by wear. Therefore, study new methods for making protective coatings on titanium is relevant. A mixture granules with tungsten carbide powder was used to prepare alloy Ti6Al4V method electrospark depositi...
