| Abstract: | SiCP/Al Composites with various volume fraction were prepared by pressureless infiltration.Hot(above melting point of matrix) compression on the composite was tested.The flow stress behavior of composite with different contents and granularitie standards was rearched.Effects of particle content and granularity on microstructure of SiCP/Al composite with high volume fraction were observed and analyzed by using SEM.The results show that: SiCP/Al Composite with Higher Fraction shows Pseudo-plastic deformation ... |
