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...

Titanium diboride is one of the candidate materials for high temperature applications and also for control rod elements in high temperature reactors. This paper presents the experimental data on the composites of B4 C-nano TiB2 that were synthesized successfully by co-precipitation methodat 1523K. Titanium tetraisopropanol, boron carbide, isopropanol and triton x-100were used as the precursor m...

Nanocomposites, where nanoscale inclusions are embedded in a matrix material, have attracted increasing research attention in recent years. Here, we limit our focus to polymer nanocomposites. Nano-reinforcements (for instance, nanoparticles, nanowires, and nanotubes) have largely disappointed us in manufacturing lightweight, high-strength, and high-toughness polymer composites because of their ...

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 ...

Aluminum-based alloy composites with high strength and low density can be used in corrosive environments. In this research, the nano-powders of A16061 alloy and A16061/TiB2 composite were synthesized by mechanical alloying (MA) method. Then, A16061 /TiB2 nano-composite bulk samples were prepared at laboratory scale by hot extrusion approach. Transmission electron microscopy (TEM) and X-ray diff...

B4C and its composites with TiB2 as second phase continues to be extensively used as the preferred ceramic material in military applications as armor systems for absorbing and dissipating kinetic energy from high velocity projectiles. It also exhibits a high melting point (2427 °C), and high neutron absorption cross section. Pressureless sintering of the B 4C-nanoTiB2 nanocomposite using small ...

The (TiB2+TiC)/AlSi10Mg composite powders with 1.5 wt% nano-TiB2 particles and nano-TiC were prepared by ball milling. Aluminum matrix composites (AMCs) reinforced TiB2 TiC fabricated via SLM optimal processing parameters. showed a very high ultimate tensile strength ∼552.4 MP excellent ductility ∼12%, which is 40.3% 166.7% higher than that of unreinforced AlSi10Mg, respectively. effects nanopa...
