| Abstract: | Stresses induced due to thermal mismatch between the metal matrix and the ceramic
reinforcement in metal matrix composite may impart plastic deformation to the matrix there by
resulting in a reduction of the residual stresses. Thermal mismatch strains also may quite often
crack the matrix resulting in a relaxation of the residual stresses.
The interface in MMCs is a porous, non-crystalline portion in comparison with the matrix or the
reinforcement (metal matrix and ceramic reinforcement in this case). Therefore residual stresses
are readily released at the porous and non-crystalline interface as a result of which when particle
density is high, i.e. in regions which are particle starved, meaning the availability of the interface
is limited, particle fracturing is predominating.
In the present investigation ring-shaped Al-SiCp MMCs are fabricated in the solid state
processing route. The sintering temperature and time of holding at the sintering temperature are
varied and the s... |
