Additive manufacturing (or 3D printing) opens the possibility of creating new designs and manufacturing objects with new materials rapidly and economically. Particularly for use with polymers and polymer composites, simple printers can make high quality products, and these can be produced easily in offices, schools and in workshops and laboratories. This technology has opened a route for many t...

Abstract Recently, silicon carbide–boron carbide composite ceramics have attracted more and attention. The most important achievements of the should be applied in terms mechanical, physical, chemical for use various advanced industries, such as armor plates, nozzles, abrasive tools, mechanical seals, etc. To prepare with good performance, synthesis powders is basis. approaches are systematicall...

A metal-based matrix is usually used for the fabrication of diamond bits in order to achieve favorable properties and easy processing. In the effort to reduce the cost and to attain the desired bit properties, researchers have brought more attention to diamond composites. In this paper, Fe-based impregnated diamond composites for drill bits were fabricated by using a pressureless infiltration s...

Boron carbide is super-strong and has many important engineering applications such as body armor cutting tools. However, the extended of boron have been limited by its low fracture toughness arising from anomalous brittle failure when subjected to hypervelocity impact or under high pressure. This abnormal directly related formation a tiny amorphous shear band 2–3 nm in width several hundred len...
