| Abstract: | The directional solidification of aluminium matrix composites, reinforced bycarbon fiber with non-wettable SiC coatings,was presented in this paper. The functions ofdirectional solidification velocity to the solidification processing and morphology werestudied,and the columnar dendrite with different arm spacing and cellular crystal wereobtained in the matrix between the fiber bunches,It has been found that the tensile strengthof non-wettable system composites decreased after directional solidification,and themechanism was also probed. |
