The properties of Mo/B4C multilayer X-ray mirrors with periods 3.74 – 3.84 nm are studied in this work. dependences the transmission band, reflection coefficient and magnitude internal stresses on ratio material thicknesses period were investigated. results a study effect thermal annealing structural parameters reflective characteristics also presented paper.

The current work seeks to discover and choose the proper friction stir processing (FSP) settings for aluminum alloy 7075 surface composites enhanced by adding three unique nanoparticles of titanium dioxide (TiO2), B4C, graphene superior performance. FSP is only method that produces higher amounts particle distribution nanoscale reinforcing. For sample fabrication, a special relatively high rota...

The design of the cavity and shielding system of the Prometheus reactors was undertaken by UCLA in conjunction with an IFE conceptual reactor study led by McDonnell Douglas. A wetted wall by a thin lead film was used as part of the first wall system (FWS) designated to protect the cavity against the microexplosions. The FWS is attached to the blanket/reflector/plena (B/R/P) system. For low acti...

Bu çalışmada, bor karbür (B4C) tozu ve çeşitli polimerik bağlayıcılar kullanılarak toz enjeksiyon kalıplama (TEK) besleme stoğu hazırlanmıştır. B4C ilavesinin stoğunundaki kritik yükleme değeri, reolojik bağlayıcı giderme davranışları üzerindeki etkisi farklı sıcaklıklarda rotasyonel reometre cihazı incelenmiştir. Hacimce %2,5’luk artışla %50-60 aralığında gerçekleştirilen incelemeler sonucunda...
