In this study, to evaluate the effect of boron carbide (B4C) addition on wear performance aluminum (Al), Al6061 and 5, 10, 20 vol.% B4C/Al6061 composites were manufactured using stir casting hot rolling processes. B4C particles randomly dispersed during process; then, arranged in direction a process further improve dispersion resistance composites. Furthermore, continuous interfacial layer betw...

Properties of Al/TiB2 heterophase interfaces are investigated by means atomic-scale calculations. Focusing on practically important (111)Al//(0001)TiB2basal interfaces, our study allows to clarify various ambiguities present in the literature when calculating coherent interface energies non-binary systems: (i) while neglected earlier works Al/TiB2, elasticity effects properly taken into account...

A series of boron nitride nanotubes (BNNTs)/ carbide (B4C) composite ceramics were prepared using spark plasma sintering (SPS) technology, which uses B4C powders as the matrix and BNNTs toughening phase. X-ray diffraction (XRD) scanning electron microscope (SEM) then used to characterize ceramic samples. The effects temperature, content, particle size on microstructure mechanical properties inv...

in this research, b4c-ni cermet coating was sprayed on the surface of 4130 steel from b4c and ni feed-stockpowders using high velocity oxy-fuel (hvof) method. in order to characterize the tribological behavior of thecoating, ball on disk wear tests were done at the ambient temperature and under the loads of 1, 3 and 5 n.phase analysis of the coating after spraying was studied by x-ray diffracto...

In the current study, effect of different B4C additions (0, 2.5, 5, and 10 wt%) on microstructural, solidification behavior, mechanical, tribological properties Al-20%Mg2Si composite were studied by means scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Vickers hardness, tensile, dry sliding wear tests. The cooling curve thermal ana...
