Study on Influence of Process Parameters in Hot Rolling of Al 7178 Metal Matrix Materials

Abstract

Aluminium and its alloys are in demand for the manufacturing of components due to their high strength to weight ratio. As the technology is advanced the demand for high strength to weight ratio is increased exponentially. Many researchers are explore alternatives to pure aluminium by way of adding silicon and metal matrix of Mg, SiC and Al2 O3 . The present work aims at preparation of optimized Al7178 by stir casting process and extruding to preparation of aluminium matrix materials consisting silicon carbide and aluminium oxide (Al2 O3 ) powder of 40a�m particle size at 6% weight percentage with a objective of investing the influence of process parameters of hot rolling process. Investigation is undertaken in order to minimize the rolling force of Al7178 aluminium metal matrix in hot rolling forming process where in the process parameters inlet thickness, rolling speed, percentage reduction of thickness, rolling temperature are considered as input parameters. Experimentation on hot rolling process concludes that 6% weight percentage of SiC and Al203 needs minimum rolling force 2.6 and 1.3 kN corresponding to 9mm inlet thickness, 15rpm rolling speed, 10% of thickness reduction at rolling temperature of 600ᵒC.
