Composites by aluminum infiltration of porous silicon carbide derived from wood precursors
نویسندگان
چکیده
Composites were fabricated by infiltration of molten Al–13Si–9Mg into porous SiC derived from wood. The composite microstructure retains the heterogeneous orthorhombic symmetry of the initial wood material. As compared to the uninfiltrated SiC preform, the composite shows much improved transverse compressive strength and stiffness, resulting in reduced anisotropy. 2006 Acta Materialia Inc.

MECHANICAL BEHAVIOR OF INTERPENETRATING Al-SiC COMPOSITES DERIVED FROM WOOD TEMPLATES
Biomorphic silicon carbide stands as a new class of materials fabricated by reactive infiltration of molten silicon in carbonaceous preforms obtained from wood pyrolysis [1]. The basic material is a Si/SiC composite, in which the SiC forms a skeleton that replicates the wood microstructure and the unreacted Si fills the pores. Silicon can be removed from the composite creating a highly porous S...

In this investigation ‚the fracture toughness of A356 containing15%SiC composite was studied. Al/SiC composites have been considered because of their mechanical and erosion properties .Low fracture toughness in Al/SiC as compared with Aluminium alloys is one of its disadvantage. In this study at first A356 alloy was melted in a smelting electrical furnace then poured into the mould. A356-15% Si...

Dense silicon carbide (SiC) matrix composites with SiC whiskers and particles as reinforcement were prepared by infiltrating molten Si at 1550 °C into porous preforms composed of pyrolysed rice husks (RHs) and extra added SiC powder in different ratios. The Vickers hardness of the composites showed an increase from 18.6 to 21.3 GPa when the amount of SiC added in the preforms was 20% (w/w), and...
