Abstract


The aim of the present investigation has used to predict the stress formability index and the pore closure behavior of the sintered Al-SiC composites. Aluminium composite powder reinforced by silicon carbide containing 10% and 20% SiC.  Three different sintering time intervals were proposed namely 1.5, 3 and 4.5 hrs at 605°C were completely investigated. The effect of SiC addition on the formability stress index value was studied. For higher SiC addition preforms the formability stress index reaches very high value. With increasing sintering time the formability stress index increases due to a decrease pore. It was enlightened to obtain a pore closure verification three novel stress based pore closure rate indices were proposed and analysed for all the above said preforms and their variations with respect to their relative density were plotted and discussed. The Formability stress index value were evaluated and discussed in terms of matrix and geometric work hardenings.
