Investigation of mechanical properties of B₄C/SiC/Al₂O₃ particle reinforced Al2024 hybrid composites

Modification of the model for calculating the long SiC fibre-reinforced metal matrix composites transverse strength and study for interfacial influences

“…The final damage of unidirectional composites under transverse loading has been demonstrated to be caused some reasons,they are interfacial cracking and matrix damage, mainly due to the stress concentration resulting from the addition of fibres to the matrix [6]; therefore, the calculation of the transverse strength of long SiC fibre-reinforced titanium matrix composites m into account the effect of stress concentration [13]. However, the predicted transverse strength results are still much larger than the experimental transverse strength [14,15]. On this basis, the model needs to be refined to fully account for the effects caused by the interface.…”

Erosion behavior and mechanism of Cu-B4C composites under arc discharge in different atmospheres

“…Tian et al [19] found that the addition of appropriate amounts of B 4 C particles to copper-based graphite composites effectively increased the hardness and compressive yield strength and reduced the porosity and wear loss of composites. Moreover, the excellent chemical inertness and thermal stability of B 4 C ensure that no compounds are generated at high temperatures that would decrease the electrical properties of the material, so it is considered a good candidate for the reinforcement phase of metals, ceramics and plastic matrixes [20][21][22].…”
