The investigation of mechanical properties of B4C-reinforced AlSi7 foams

, 2015
In this study, the mechanical properties of B4C-reinforced AlSi7 foams produced by using a powder metallurgy method were investigated. For this purpose, Al foams containing B4C at various ratios (0, 2, 4 and 6 %) were prepared with dimensions of 30 × 30 ×

The effect of B4C particle size on the reaction process and product in the Cu–Zr–B4C system

, 2015
ZrC and ZrB2 were prepared by self-propagating high-temperature synthesis in a Cu–Zr–B4C system. We explored the influence of B4C particle size on the reaction process, phase composition and microstructure of the products.

PARTICLE SIZE-DEPENDENT PULVERIZATION OF B4C AND GENERATION OF B4C/STS NANOPARTICLES USED FOR NEUTRON ABSORBING COMPOSITES

, 2014
Pulverization of two different sized micro-B4C particles (∼10 μm and ∼150 μm) was investigated using a STS based high energy ball milling system. Shapes, generation of the impurities, and reduction of the particle size dependent on milling time and ...

Optimization of PMEDM process parameters for B4C and B4C+SiC reinforced AA7075 composites

Journal of Engineering Research
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 ...
