Bu çalışmada, ağırlıkça %10, %20 ve %40 Bor Karbür (B4C) içerikli Al matris partiküllerin kompakt malzemelerin üretimi karakterizasyonu gerçekleştirilmiştir. B4C takviyeli elektriksel iletkenlik değerleri en düşük 6,97 %IACS yüksek 20,73 olarak belirlenmiştir. Deneysel çalışmalar sonucunda, mikro yapıda artan takviyesinin yapının yoğunluğunu azaltma sertliğini arttırma noktasında olumlu etkisi ...

In this article, a boron carbide particle (B4C) reinforced AA2014 surface composite was first fabricated by friction-stir processing (FSP) to investigate the impact of volume percentage B4C, tool rotational speed and table on tensile strength (TS) wear rate (WR). The is one important candidates for making defense aerospace components due its high minimum weight. Taguchi orthogonal array employe...

in this study, aluminum (al) matrix reinforced with micro-particles (30 µm) and nano-particles (50 nm) boron carbide (b4c) were used to prepare al-2.5%wt., b4c nano-composite and micro-composite, respectively, using mechanical alloying method. the mixed powders were mechanically milled at 5, 10, 15 and 20 hrs. the xrd results indicated that the crystallite sizes of both the micro-composite and ...

We propose a new system, namely the periodic Co/Mg multilayer system, for optics applications in the EUV range. Close to the Mg L edge, i.e., around a wavelength of 25 nm or a photon energy of 50 eV, a reflectivity of about 43% is measured at 45° for s-polarized radiation. Moreover, it appears that this system is stable over a period of time of three months. The introduction of thin boron carbi...

5-Fluorouracil (5-FU) is an anticancer drug. In this work, we have investigated the electronic properties and topological analysis of interaction between 5-FU and carbon nanocone and BN nanocone. The structural stability of isomer complexes of 5-FU with carbon nanocone and BN nanocone have been investigated for two position of interactions. We have found that the most stable complexes are forme...

Boron carbide (B4C) is of interest in the armor community due to its combination extreme hardness and low density. However, it difficult utilize these properties many applications challenges associated with forming near-net shapes B4C, combined inherent sinterability without application external pressure. In this study, highly loaded (51 vol. %) aqueous B4C suspensions were developed injection ...
