Systematic effects of carbon doping on the superconducting properties of Mg(B$_{1-x}$C$_x$)$_2$
The upper critical field, $H_{c2}$, of Mg(B$_{1-x}$C$_x$)$_2$ has been measured in order to probe the maximum magnetic field range for superconductivity that can be attained by C doping.

Planar shock compression of spark plasma sintered B4C and B4C–TiB2 ceramic composites
Blending of ceramic constituent phases enhances sinterability and performance in high strength ceramics. Here, a near fully dense blended boron carbide (B4C)–titanium diboride (TiB2) composite produced through spark plasma sintering (SPS) is probed to understand the mechanical performance under dynamic uniaxial strain, or shock compression.

Superconducting and Normal State Properties of Heavily Hole-Doped Diamond
We report measurements of the specific heat, Hall effect, upper critical field and resistivity on bulk, B-doped diamond prepared by reacting amorphous B and graphite under high-pressure/high-temperature conditions. These experiments establish unambiguous

Compatibility of refractory materials for nuclear reactor poison control systems [PDF]
Metal-clad poison rods have been considered for the control system of an advanced space power reactor concept studied at the NASA Lewis Research Center. Such control rods may be required to operate at temperatures of about 140O C.

Alüminyum matrisli, bor karbür (B4C) takviyeli kompozit malzemelerin geleneksel yöntemlerle üretiminde sıvı alüminyumun B4C partiküllerini ıslatabilirliğinin düşük olduğu bilinmektedir. Bu kompozitlerin başarılı bir şekilde üretilebilmesi için alüminyum metalinin B4C üzerindeki düşük ıslatılabilirlik probleminin çözülmesi gerekmektedir.

Fabrication and characterization of B4C nanowires and dense B4C ceramic/nanowires composite
The superior properties of boron carbide (B4C), such as high melting point, extreme hardness (ranking third after diamond and cBN), low density, good thermal and chemical resistance properties, have made it a promising material for ceramic armor applications.

Optimization of PMEDM process parameters for B4C and B4C+SiC reinforced AA7075 composites
Materials: With sufficient electrical conductivity can be successfully processed by applying the electrical discharge machining (EDM) method; however, due to the presence of non-conductive particles in composites, which have been produced by adding ceramics particles, problems such as unstable machining, low material removal rate, and high tool wear ...
