Figure 12 : Matrix failure adjacent to Al/TiC interface for Al6061+5wt% TiC composite of a/W = B/W =0.5. C ONCLUSIONS ollowing are the major conclusions: (a) The fatigue crack growth rate curve for Al6061-TiC (3wt %-7wt %) metal matrix composites fall over a narrower stress intensity range. Hence, the composites may be considered for aerospace sectors. F
