Tension experiments in vacuum were performed on a monolithic Si3N4 sample at 1375°C and a 20Vol% SiCp-Si3N4 composite sample at 1400°C using the new SMARTS diffractometer at the Los Alamos Neutron Science Center. The deep penetration of neutrons facilitated these in-situ studies. In particular, the hkl-dependent strains were measured and the results interpreted by Eshelby-based modeling for the...

Abstract In this study, the proposed experimental and second-order model for cutting forces were developed through several parameters, including speed, feed rate, depth of cut, two varying content SiCp. Cutting force was optimized RSM compared different percentages components SiCp/Al 45% 50%. ANOVA is used Quantitative evaluation, main effects plot along with evaluation using graphs plots resid...

In this work, a novel processing method called powder thixoforming was proposed to prepare composites reinforced with 50 vol % of SiC particles (SiCp) that were used for electronic packaging in order to investigate the effects of remelting duration on its microstructure and properties. Optical Microscope (OM), Scanning Electron Microscope (SEM), X-ray Diffraction (XRD) and Transmission Electron...

In the title compound, [Ti(C(8)H(13)Si)(C(11)H(21)Si(2))Cl(2)], the Ti(IV) atom is bonded to two Cl atoms, one 1,3-bis-(trimethyl-sil-yl)cyclo-penta-dienyl (Si(2)Cp) and one (trimethyl-sil-yl)cyclo-penta-dienyl ring (SiCp). The Si(2)Cp centroid-titanium distance is 2.0763 (10) Å and the SiCp centroid-titanium distance is 2.0793 (10) Å. The angle subtended at the Ti atom by the centroids of both...

In this paper, ultrasonic vibration–assisted electrical discharge machining (UEDM) is used to process SiCp/Al composite materials in order achieve a higher material removal rate (MRR) and lower surface roughness, width overcut, relative tool wear (RTWR). On the basis of studying erosion mechanism EDM material, flow field simulation study was carried out using FLUENT software. The results gap sh...
