摘要：

The present paper reports the effect of height to diameter (h/d) ratio on the deformation behaviour of Fe-Al2O3 metal matrix nanocomposites (MMNCs) during bulk processing. Sintered compacts were machined to the required size with different h/d ratios. Test specimens were subjected to deformation at room temperature under three different interfacial friction conditions such as dry, solid and liquid lubrications. Deformed specimens show a significant improvement in the density and hardness. Results also revealed the formation of a nanosize iron aluminate phase due to reactive sintering, which in turn contributes to grain refinement. Experimental density of the specimens was also verified with the theoretical density using the standard equations. It is expected that the present work will be useful in designing and developing MMNC products with better quality at competitive cost.
