Advanced ceramics are required in many applications including armor, engine components, and wear parts for abrasive, corrosive, high temperature environments. Heterogeneous structuring these materials has the potential to unlock extrinsic mechanisms that improve damage tolerance, of vital importance structural functionality. However, traditional ceramic powder processing forming techniques limi...

Mechanical property and impact resistance mechanism of bionic layered composite was investigated. Due to light weight and high strength property, white clam shell was chosen as bionic model for design of bionic layered composite. The intercoupling model between hard layer and soft layer was identical to the layered microstructure and hardness tendency of the white clam shell, which connected th...

Periodic multilayers are nowadays widely used to perform x-ray analysis in the soft x-ray range (photon energy lower than 1 keV). However, they do not permit to obtain highresolution spectra like natural or synthetic crystals. Thus, multilayers cannot resolve interferences between close x-ray lines. It has been shown and demonstrated experimentally that patterning a grating profile within a mul...

Coating technology is decisively important for metallization of ceramic materials and metal sealing technology. Previous studies have shown that the network-like structure after penetration molten aluminum can significantly improve strength joint components. However, direct coating method limited by shape substrate. To obtain a dense film on surface B4C, in this study, was deposited pulse elect...

Abstract This study deals with the selection of optimum parameters for friction stir processing Al alloy 6061-T6 reinforced a hybrid nanoparticle (B4C and SiO2) in terms their effect on mechanical properties (hardness, tensile strength, wear resistance) using Taguchi method. work was carried out under four each one running three levels; rotational speeds ( 800 , 1000 1200 ) rpm, travel 10 20 30...

There is a developing interest in efficient materials automobile and aerospace fields that involves the improvement of metal matrix composites (MMCs) with great properties which incorporate higher strength, hardness stiffness, better wear destructive resistance along thermal properties. This work deals evaluation mechanical newly developed hybrid MMC Al 5059/B4C/Al2O3 produced by stir casting m...

In this research study, the mechanical properties of several Polymer matrix composites are investigated. These multi-phase materials in which reinforcing properly mixed with a polymer matrix. More precisely, Nylon 6 reinforced 5, 15 and 25 wt. % silicon carbide (SiC) boron (B4C), prepared by means an injection moulding process at three different pressures considered. Specific attention is paid ...
