“…4(a) and (b), both the composite and matrix alloy show greater plastic deformation, the plots of the hysteresis loop are big and stable in the initial-life. At the half-life, the tendency for hardening in com- posite and alloy is found to increase with strain amplitude, which was also observed by Han et al [17] in as-cast SiC p /2024Al. This is due to the fact that stress response to cyclic straining depends on its initial microstructure and deformation history [10].…”

Ni-P coated Si 3 N 4 reinforced Al6061 composites were fabricated by stir casting technique. Silicon nitride particles were varied in steps of 2 from 6 wt.% to 10 wt.%. Cast matrix alloy and developed composites were hot forged at a temperature of 500 • C using a 300T hydraulic hammer. Both as cast, hot forged matrix alloy and its composites were subjected to microstructural studies and fatigue strength tests. Microstructural studies reveal even distribution of silicon nitride particles with excellent bond between the matrix and reinforcement in both as cast and hot forged condition. It is observed that, increased content of reinforcement in both as cast and hot forged composites do result in significant improvement in fatigue strength. However, when compared with as cast matrix alloy and its composites, hot forged alloy and its composites exhibit higher fatigue strength. Both as cast and hot forged composites demonstrate improved fatigue strength when compared with the unreinforced alloys under identical test conditions. Fractured surfaces were examined using scanning electron microscopy (SEM) for the possible fracture mechanisms.

“…Discontinuously reinforced aluminum matrix composites (DRAMCs) have been of interest as engineering materials because of their improved strength, stiffness and superior wear resistance when compared with their unreinforced alloys (Han et al, 1999). Potential application of DRAMCs in automobile sector includes components like piston cylinder liner brake drums, crankshafts, etc.…”
